vcs mismatch 的修复过程 一般初仿真,如果只是验证scan的功能的话,可以加上+ncseq_udp_delay+1ns和+ncdelay_mode_zero来做。这样flipflop的输出都是固定一个ns的延时,而线和组合逻辑的delay都是0. 但是一定要跑后仿真,PrimeTime输出scan的sdf(一般是double check hold),反标后再跑,由于ncverilog不支持负的hold,...
-v filename:Specifies a Verilog library file. VCS looks in this file for definitions of the module and UDP instances that VCS found in your source code, but for which it did not find the corresponding module or UDP definitions in your source code. 此选项使您能够指定一个Verilog库文件。VCS...
Ignores SystemVerilog assertion subsequences containing past operators that have not yet eclipsed the history threshold. vpiSeqBegin Enables you to see the simulation time that a SystemVerilog assertion sequence starts when using Debussy. vpiSeqFailEnables you to see the simulation time that a ...
