Accounting Policies [Abstract]
Basis of presentation and consolidation and Emerging growth company status	Basis of presentation and consolidation The accompanying condensed consolidated financial statements have been prepared in accordance with U.S. Generally Accepted Accounting Principles ("GAAP") and include the accounts of Silvaco and all of the Company's wholly owned subsidiaries with operations in North America, Europe, Asia and South America. All intercompany transactions and balances have been eliminated upon consolidation. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been omitted from these condensed consolidated financial statements, as permitted by Securities and Exchange Commission (“SEC”) rules and regulations. Accordingly, these condensed consolidated financial statements should be read in conjunction with its audited consolidated financial statements for the year ended December 31, 2023 and the related notes thereto included in the Company’s final prospectus relating to the initial public offering, dated May 8, 2024 (the “Prospectus”), relating to the Registration Statement on Form S-1 (File No. 333-278666), as amended (“Registration Statement”), filed with the SEC on May 10, 2024, pursuant to Rule 424(b)(4) under the Securities Act of 1933, as amended (“Securities Act”). The December 31, 2023 condensed consolidated balance sheet was derived from the audited consolidated financial statements as of that date. In management’s opinion, the unaudited condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the condensed consolidated financial statements. The results of operations for the three months ended March 31, 2024 are not necessarily indicative of the Company’s operating results to be expected for the full fiscal year or any other future interim or annual period.
Revision of Prior Financial Statements	Revision of Prior Financial Statements For the three months ended March 31, 2023, accrued expenses and general and administrative expenses were understated by $0.2 million in the Company’s condensed consolidated balance sheet and condensed consolidated statement of income, respectively, due to certain accruals for professional services rendered not being recorded. The Company has determined that such errors are immaterial and has increased accrued expenses and other current liabilities and general and administrative expenses to correct these immaterial errors.
Use of estimates	Use of estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Estimates also affect the amounts of revenue and expenses during the reported periods. The Company’s most significant estimates relate to revenue recognition. Other estimates include, but are not limited to, accounts receivable allowances, stock-based compensation, valuation of goodwill and other intangible assets, contingent consideration, uncertain tax positions and income taxes. Actual results could differ from those estimates.
Stock split	Stock split On April 29, 2024, the Company effected a 1-for-2 reverse split of its common stock. Upon the effectiveness of the reverse stock split, (i) every two shares of outstanding common stock was combined into a single share of common stock, (ii) the number of shares of common stock to be granted upon the vesting of each outstanding restricted stock unit (“RSU”) was proportionally decreased on a 2-for-1 basis, and (iii) the fair value of each outstanding RSU was proportionately increased on a 1-for-2 basis. All of the outstanding common stock share numbers, RSUs, RSU fair values and per share amounts have been adjusted, on a retroactive basis, to reflect this 1-for-2 reverse stock split for all periods presented. The par value per share and authorized number of shares of common stock were not adjusted as a result of the reverse stock split.
Concentrations of credit risk	Concentrations of credit risk As of March 31, 2024, none of the Company’s customers represented more than 10% of the Company’s accounts receivable. As of December 31, 2023, two customers represented 20% and 15% of the Company’s accounts receivable. During the three months ended March 31, 2024 one customer represented 11% of the Company’s total revenue. None of the Company’s customers represented more than 10% of the Company’s total revenue for the three months ended March 31, 2023. In addition to the concentration of credit risk with respect to trade receivables, the Company's cash on deposit with financial institutions is also exposed to concentration risk. The Company's cash on deposit with financial institutions are insured through various public and private bank deposit insurance programs, foreign and domestic; however, a significant portion of cash balances held as of March 31, 2024 and December 31, 2023 exceeded insured limits. As of March 31, 2024, $3.0 million, or 52%, of the Company’s cash was maintained with one financial institution, where the Company’s current deposits are in excess of federally insured limits. Past macroeconomic conditions have resulted in the actual or perceived financial distress of many financial institutions, including the failures of Silicon Valley Bank, Signature Bank, First Republic Bank and the UBS takeover of Credit Suisse. If the financial institutions with whom the Company does business were to be placed into receivership, the Company may be unable to access the cash it has on deposit with such institutions. If the Company is unable to access its cash as needed, the Company’s financial position and ability to operate its business could be adversely affected.
Allowance for credit losses	Allowance for credit losses The Company assesses its ability to collect outstanding receivables and contract assets and provides customer-specific allowances, allowances for credit losses for the portion of receivables and contract assets that are estimated to be uncollectible. Allowances for credit losses are based on historical collection experience and expected credit losses, customer specific financial condition, current economic trends in the customer's industry and geographic region, changes in customer demand and the overall economic climate in the market the Company serves. Provisions for the allowance for expected credit losses attributable to bad debt are recorded as general and administrative expenses. Account balances deemed uncollectible are written off, net of actual recoveries. If circumstances related to specific customers or the market the Company serves change, the Company’s estimate of the recoverability of its accounts receivable and contract assets could be further adjusted. The Company does not have any material account receivable or contract asset balances that are past due and has not written off any significant balances in its portfolio against the allowance for credit losses for the periods presented.
Foreign currencies	Foreign currencies The financial statements of Silvaco's international subsidiaries with local functional currencies are translated to U.S. dollars upon consolidation. Assets and liabilities are translated at the effective exchange rate on the balance sheet date. Results of operations are translated at average exchange rates, which approximate rates in effect when the underlying transactions occur. For the three months ended March 31, 2024 and 2023, the Company recorded foreign currency translation adjustments of $(0.2) million and $0.1 million, respectively, within accumulated other comprehensive loss. Certain sales and intercompany transactions are denominated in foreign currencies. These transactions are recorded in functional currency at the appropriate exchange rate on the transaction date. Monetary assets and liabilities denominated in a currency other than the Company's functional currency or its subsidiaries' functional currencies are remeasured at the effective exchange rate on the balance sheet date. Gains and losses resulting from foreign exchange transactions are included in interest and other expense, net.
Accumulated other comprehensive loss	Accumulated other comprehensive loss Accumulated other comprehensive loss is composed entirely of foreign currency translation adjustments.
Earnings per share (EPS)	Earnings per share (EPS) Basic EPS is computed based on the weighted average number of shares of common stock outstanding. Diluted EPS is computed based on the weighted average number of common shares outstanding increased by dilutive common stock equivalents, attributable to RSU grants.
Recently adopted accounting pronouncements and Accounting guidance issued and not yet adopted	Recently adopted accounting pronouncements In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ASU 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. This ASU simplifies accounting for convertible instruments by removing major separation models required under current GAAP. The Company adopted this standard on January 1, 2024 and the adoption did not impact the condensed consolidated financial statements. Accounting guidance issued and not yet adopted In November 2023, the FASB issued Accounting Standards Update ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires disclosure of incremental segment information on an interim and annual basis. This ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal periods beginning after December 15, 2024, and requires retrospective application to all prior periods presented in the financial statements. The Company is currently evaluating the impact of the guidance on the condensed consolidated financial statements and related disclosures. In December 2023, the FASB issued ASU No. 2023-09 (“ASU 2023-09”), Income Taxes (Topic 740): Improvement to Income Tax Disclosures to enhance the transparency and decision usefulness of income tax disclosures. ASU 2023-09 is effective for annual periods beginning after December 15, 2024 on a prospective basis. Early adoption is permitted. The Company is currently evaluating the impact of this accounting standard update on the condensed consolidated financial statements and related disclosures.
Revenue	The Company's revenue is derived principally from contracts which promise to deliver combinations of software licensing and related maintenance and services, which are accounted for as separate performance obligations with differing revenue recognition patterns. The transaction price is allocated to each distinct performance obligation based on the relative standalone selling price. Software license revenue consists of the Company’s software sold under a software license. Revenue related to stand-alone software applications are generally recognized upon shipment and delivery of license keys. For certain arrangements revenue is recognized based on usage or ratably over the term of the arrangement. Maintenance and service revenue consists of both maintenance revenues and professional services revenues which is recognized based on usage or ratably over the term of the arrangement. Timing of revenue recognition may differ from the timing of invoicing to customers. The Company records a contract asset when revenue is recognized prior to invoicing, an accounts receivable upon invoicing or deferred revenue when invoicing precedes revenue recognition. Customer contracts The Company accounts for a contract with a customer when both parties have approved the contract and are committed to perform their respective obligations, each party’s rights and payment terms can be identified, the contract has commercial substance, and it is probable the Company will collect substantially all of the consideration it is entitled to. Revenue is recognized when, or as, performance obligations are satisfied by transferring control of a promised software or providing service to a customer. For multi-year software licenses, the Company generally invoices customers annually at the beginning of each annual coverage period.
