Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies During the nine months ended October 1, 2017, there were no changes in the Company's significant accounting policies from its disclosure in the Annual Report on Form 10-K for the year ended January 1, 2017. For a discussion of the significant accounting policies, please see the Annual Report on Form 10-K for the fiscal year ended January 1, 2017, filed with the SEC on March 9, 2017. In the first quarter of 2017, the Company started recognizing revenue from licensing eFPGA Intellectual Property, or IP. Following is the Company's revenue recognition policy for IP licensing. The Company accounts for its IP license revenues and related services in accordance with Financial Accounting Standard Board or FASB Accounting Standards Codification or ASC No. 985-605, Software Revenue Recognition. Revenues are recognized when persuasive evidence of an arrangement exists and no further obligation exists, delivery has occurred, the license fee is fixed or determinable, and collection is reasonably assured. A license may be perpetual or time limited in its application. The Company’s IP license agreement contains multiple elements including post-contract customer support. For multiple element arrangements involving software and other software-related deliverables, vendor-specific objective evidence of fair value (“VSOE”) must exist to allocate the total fee among all delivered and non-essential undelivered elements of the arrangement. If undelivered elements of the arrangement are essential to the functionality of the product, revenue is deferred until the essential elements are delivered. If VSOE does not exist for one or more non-essential undelivered elements, revenue is deferred until such evidence exists for the undelivered elements, or until all elements are delivered, whichever is earlier. VSOE of each element is based on historical evidence of stand-alone sales of these elements to third parties including substantive renewal rate as stated in the agreement. When VSOE does not exist for undelivered items, the entire arrangement fee is recognized ratably over the performance period. As the IP license agreement entered into during the quarter ended April 2, 2017 is the first such revenue agreement, no VSOE exists for any of the elements. Accordingly, the Company is recognizing revenue associated with this contract ratably over the performance period. New Accounting Pronouncements Recently adopted accounting pronouncements: In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330): Simplifying the measurement of Inventory, which amends the accounting guidance on the valuation of inventory. The guidance requires an entity to measure in scope inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The amendment applies to inventory valued at first-in, first-out or average cost. This guidance is effective for reporting periods beginning after December 15, 2016, including interim periods within those fiscal years. The Company adopted this guidance in the first quarter of 2017 prospectively with no material effect on the consolidated financial statements. Recently issued accounting pronouncements not yet adopted: In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five-step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing GAAP. In applying this new guidance to contracts within its scope, an entity will: (1) identify the contract(s) with a customer, (2) identify the performance obligation in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies a performance obligation. Additionally, this new guidance would require significantly expanded disclosures about revenue. The new standard allows for two transition methods - (i) a full retrospective method applied to each prior reporting period presented, or (ii) a modified retrospective method applied with the cumulative effect of adoption recognized on adoption. In July 2015, the FASB approved a one-year delay in the effective date by issuing ASU 2015-09, Revenue from Contracts with customers. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. In March, April, May and December 2016, the FASB issued ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20, respectively, which provide supplemental guidance and clarification to ASU 2014-09. The Company is required to adopt ASU 2014-09 on January 1, 2018, the first day of the Company's 2018 fiscal year. The Company currently anticipates adopting this guidance using the modified retrospective transition method. The Company is in the process of completing its assessment of the new standard’s effect on its consolidated financial statements. The Company currently believes that the timing of recognizing revenue under its contracts with customers for sales of semiconductor products will not change significantly, but the timing of revenue recognition for its IP licensing and related services will likely be impacted, after the adoption of ASU 2014-09. The Company expects to complete its evaluations of the impact of adoption of ASU 2014-09 on its financial statements as well as on its business processes, controls and systems by December 31, 2017. The Company currently does not expect this new standard to affect the Company materially. The new standard requires comprehensive disclosure of quantitative and qualitative information that enables users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The Company expects to expand its revenue disclosure upon adoption of the new standard to meet this requirement. In February 2016, the FASB issued ASU No. 2016-02, Leases. The new standard establishes a right-of-use ("ROU") model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently evaluating the impact of our pending adoption of the new standard on the consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This update clarifies how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This ASU is effective for public business entities for fiscal years beginning after December 15, 2017, and for interim periods therein with early adoption permitted and must be applied retrospectively to all periods presented. The Company is currently evaluating the impact of our pending adoption of the new standard on the consolidated financial statements. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity transfers of assets other than inventory. This update removes the requirement under which the income tax consequences of intra-entity transfers are deferred until the assets are ultimately sold to an outside party, except for transfers of inventory. The tax consequences of such transfers would be recognized in tax expense when the transfers occur. The standard is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those annual periods. Early adoption is permitted. The Company is currently evaluating the impact of adopting this guidance on the consolidated financial statements. In May 2017, the FASB issued ASU No. 2017-09, Compensation-Stock Compensation (Topic 718). ASU No. 2017-09 provides clarification on when modification accounting should be used for changes to the terms or conditions of a share-based payment award. This ASU does not change the accounting for modifications but clarifies that modification accounting guidance should only be applied if there is a change to the value, vesting conditions or award classification and would not be required if the changes are considered non-substantive. The amendments of this ASU are effective for reporting periods beginning after December 15, 2017, with early adoption permitted. The Company is currently evaluating the impact of adopting this guidance on the consolidated financial statements. Other new accounting pronouncements are disclosed on the Annual Report on Form 10-K for the fiscal year ended January 1, 2017 filed with the SEC on March 9, 2017.

Significant Accounting Policies

The Company accounts for its IP license revenues and related services in accordance with Financial Accounting Standard Board or FASB Accounting Standards Codification or ASC No. 985-605, Software Revenue Recognition.

VSOE of each element is based on historical evidence of stand-alone sales of these elements to third parties including substantive renewal rate as stated in the agreement. When VSOE does not exist for undelivered items, the entire arrangement fee is recognized ratably over the performance period.

As the IP license agreement entered into during the quarter ended April 2, 2017 is the first such revenue agreement, no VSOE exists for any of the elements. Accordingly, the Company is recognizing revenue associated with this contract ratably over the performance period.
