《芯课程》加速编译的优选手段VCS Partition Compile 课程概要 随着科技的进步,现在的芯片越来越复杂,规模越来越庞大,提高编译速度的需求也越来越迫切,新思科技(Synopsys)随之推出了全新技术的编译手段,让客户可以在既有编译flow基础上,做很少的一点改变,就能提高3~5倍的初次编译速度,提高5~10倍的再次编译速度。 目前...
这就用到了分块编译(partition compile)。 vcs分块编译(partition compile)参数讲解 分块编译的本质就是将需要编译的代码文件拆分成独立的块,只有当块中的文件更新的时候才会重新编译该块中的文件,理论上我们拆的块越细,需要重新编译的文件就少,但造成的结果就是仿真器遍历这些块的时候要消耗额外的系统时间,所以说...
(1)shell脚本 通常shell或makefile脚本调用vcs和verdi,(粗略讲一下是怎么调用的,具体需要对脚本进行学习) 直接调用在终端下调用vcs的命令为 vcs -timescale=1ns/1ns -sverilog +v2k -Mupdate -f verilog_file.f -o adder_top -l compile.log 脚本下写为 vcs -timescale=1ns/1ns \ #设置仿真精度 -...
recording the transition times and values of nets and registers in all modules defined under the `celldefine compiler directive or defined in a library that you specify with the -v or -y compile-time options. 1 disablesrecording the transition times and values of nets and registers in all ...
synopsys vcs 软件是仿真和验证的软件,必须掌握。 vcs 即 verilog compile simulator 支持 verilog, systemVerilog, openvera, systemC等语言,同时也有代码覆盖率检测等功能。 可以合第三方软件集合使用,例如 Vera , Debussy ,Specman 等等。 在linux 下调用vcs,需要设置相应的环境变量。

VCS的仿真选项分编译(compile-time)选项和运行(run-time)选项。编译选项用于RTL/TB的编译,一遍是编译了就定了,不能在仿真中更改其特性,例如define等等。 2024-01-06 10:19:49 Vivado中的Incremental Compile增量编译技术详解 Incremental Compile增量编译是Vivado提供的一项高阶功能。目的旨在当设计微小的改变时,重用...
features such as NLP, X-Propagation simulation, and Verdi®debug with parallel FSDB continue to work as before with no changes necessary to the design or testbenches. Furthermore, intelligent native FGP in VCS delivers the performance boost with minimal impact on compile time and memory usage....
coverage database directory By default VCS does not compile the following for coverage: • The source code in Verilog library directories • Verilog library files • Any module defined under the celldefine compiler directive yv For compiling for coverage source code from Verilog libraries. ...
enabling us to significantly improve overall productivity as well as accelerate new product development projects. The ability to natively compile in VCS and leverage unified debug in Verdi, alongside industry-wide recognition of VC SpyGlass for validating our RTL for multiple foundries and customers made...
