摘要: 隨著工藝尺寸的不斷縮小,電路規模的不斷復雜化以及版圖中寄生規模的不斷增大,在一些大規模的后仿驗證過程中,Cadence公司提供的模擬全精度仿真器Spectre/APS/APS RF已不能滿足需求。針對這一問題,Cadence于2019年推出APS的下一代模擬全精度仿真器Spectre X,在實際使用過程中發現其對普通模擬仿真性能提升明顯并且基本保持了APS的仿真精度。2020年,Cadence推出其APS RF的下一代仿真器Spectre X RF 仿真器。RF仿真在整體仿真驗證流程中同樣占據很大一部分,在將其應用到實際項目前,需要與APS RF對比其性能和速度。介紹了Spectre X RF的用法,并重點介紹在幾種采用不同工藝的RFIC設計中,仿真器Spectre APS RF與Spectre X RF仿真性能與精度的對比情況。

Abstract: With the continuous shrinking of process nodes, the continuous complexity of the circuits designs and the increasing size of the parasitics from layout, the analog FULL-SPICE simulator Spectre/APS/APS RF provided by Cadence can no longer meet the demand in some large-scale post-simulation verification projects. In response to this problem, Cadence launched APS′s next-generation analog full-spice simulator Spectre X in 2019. It was found that it has significant performance improvement on general analog simulations while maintained the proven golden accuracy of APS. In 2020, Cadence launched its Spectre X RF simulator, the next-generation simulator of APS RF. RF simulation also occupies a large part of our overall simulation verification works. Before applying it to actual projects, it is necessary to compare its performance and accuracy with APS RF. This article mainly introduces the usage of Spectre X RF, and focuses on the comparison of simulation performance and accuracy between Spectre APS RF and Spectre X RF in several RFIC designs using different processes.

隨著模擬電路復雜性增大以及工藝尺寸不斷減小,寄生規模不斷增大。模擬下變頻電路是通信鏈路中的接收機模塊的重要電路模塊,其中包含的射頻前端電路,在設計過程中,代入后仿寄生參數后,還需要進行多次RF仿真。仿真速度對設計影響較大,另一方面,受限于服務器性能限制,無法滿足部分大規模小尺寸模擬射頻電路內存需求。
Spectre X RF仿真器是Cadence于2020年推出的新一代仿真器,能提升仿真速度、優化內存,能有效解決目前射頻前端RF仿真中仿真速度過慢、服務器性能需求過高的問題。
在應用Spectre X RF之前,需對其進行評估,本文在三個主流工藝下,在模擬下變頻模塊中,對比Spectre APS RF和Spectre X RF的精度、內存和速度。
