VCS编译VERA产生的文件时VMC错误

zhalvin

使用"vera -proj filename.proj"后产生.v文件，然后使用"VCS  *.v"命令，提示
"Error-[UST] Undefined system task
                     Undefined System Task call to '$vmc_init' "
类似的错，有函数的，有任务的。
找了下该类任务和函数在vera安装文件夹下的lib以及lib下的vlog文件夹下vmc_veri_funext.h文件中有定义。

请问该怎么解决这个问题？谢谢

顺顺便问下，VMC有关的函数和任务是做什么用的，谢谢？

vera生成的.vshell文件中，有很多的类似$vmc_init, $vmc_system_clock这样的task，它们都是干什么的？还有他们有很多参数，都是什么意思？请大虾指点一下

zhalvin

vshell calls the Vera simulator procedure “vmc_init” through the PLI. vmc_init performs the following five major functions:
i) it loads the Vera assembly language program to be executed by the Vera simulator,
ii) it sets up certain nodes of the Verilog model as callback nodes,
iii) it creates a “master” context of level 0 , which we shall also refer to as “context( 0 ),” for the execution of the main Vera language program,
iv) it places context( 0 ) on “the run queue” of the Vera simulator which holds all Vera language contexts waiting to be run and
v) it calls “vera_main,” the main routine of the Vera simulator.
The nodes which vmc_init establishes as callback nodes in step (ii) are typically: i) the Verilog model's Vera system clock, and ii) those clocks specified by Vera language interface statements.

这么低级的错误竟然也犯了。。。无语

hi,我昨天也遇到了相似的情况，从下午3点搞到晚上8点也没有解决，能不能分享下你的宝贵经验啊？
谢谢

vmc生成模型延时启动就应该没问题了
