[cpp] view plaincopyprint? success报告成功匹配 Enables reporting of successful matches, and successes on cover statements, in addition to failures. The default is to report only failures. filter过滤掉空成功。 Blocks reporting of trivial implication successes. These happen when an implication construct registers a success only because the precondition (antecedent) portion is false (and so the consequent portion is not checked). With this option, reporting only shows successes in which the whole expression matches. -assert filtersuccess经常两者结合起来用。注意用时在filtersuccess前加上-assert maxsuccessN Limits the total number of reported successes to N. You must supply N, otherwise no limit is set. VCS continues to monitor assertions even after the limit is reached. -assert maxsuccess3 -l filename logfile文件名 Specifies a file where VCS records compilation messages. If you also enter the -R or -RI option, VCS records messages from both compilation and simulation in the same file. -assert enable_diag Enables further control of results reporting with runtime options -sverilog Enables the use of SystemVerilog code. -cm assert Compiles for SystemVerilog assertions coverage. -cm is not a new compile-time option but the assert argument is new. This option and argument must also be entered at runtime. vcs *.v *.sva -sverilog \ defineenable_blk_assertions \ definetb_sva \ defineslv_fc \ defineslv_doc \ -PP -assert enable_diag -cm assert \ -l compile.log simv -l run.log -assert filtersuccess -assert maxsuccess3 VCS对verilog模型进行仿真包括两个步骤: 1. 编译verilog文件成为一个可执行的二进制文件命令为: {1}gt; vcs source_files 2. 运行该可执行文件 {1}gt; ./simv 类似于NC, 也有单命令行的方式: {1}gt; vcs source_files -R -R 命令表示, 编译后立即执行. -cm line|cond|fsm|tgl|obc|path 设定coverage的方式 A few more compile options are significant: 1. if RVM class libs are used in the OV code, this is required: -ntb_opts rvm 2. VMM classes, vmm_ macros can be used in SV; and rvm_ macros in OV package are automatically translated to vmm_ equivalents if this is also added -ntb_opts interop -ntb_opts rvm -lca 这是VCS的参数表示使用VCS的“用户限制使用”的功能即VCS提供的一些功能是他们还没有经过充分测试还没有发布的如果你想使用这些功能就要加上 -lca参数。 incdirdirectory Specifies the directory or directories that VCS searches for include files used in the include compiler directive. More than one directory may be specified, separated by . plusarg_save Some runtime options must be preceded by the plusarg_save option for VCS to compile them into the executable. You can specify this option either on the vcs command line or in the file specified with the -f or -F option. You can also enter the following runtime options on the vcs command line or in the file that you specify with the -f or -F compile-time option, so that VCS compiles them into the simv executable, BUT you must precede them with the plusarg_save compile-time option: cfgfile override_model_delays vcsdumpoff vcsdumpon vcsdumpvarsoff vcsgrwavesoff vcsignorestop vcslearnpli vcsmipdnoalias vcsnostdout vcsstop vera_load vera_mload vpdbufsize vpddrivers vpdfile vpdfilesize vpdnocompress vpdnostrengths vpdports vpdupdate -ntb_opts dtm You enable testbench constructs outside programs with the -ntb_opts dtm compile-time option and keyword argument. The testbench constructs that you can enter outside programs with this option are as follows:classes associative arrays dynamic arrays SystemVerilog named events 工作状态: 建立仿真环境 VCS是Synopsys公司的仿真工具.
