system c的Core Dump问题

supermanqc

老铁们，最近在研究system c+uvm+vcs的联合仿真问题。

system c 版本：2.3.1
uvm 版本： 1.2a
vcs版本：2018

问题描述如下：

0 s(0): stim_axi_master0.stim_axi_master0.stim_axi_master0.stim_axi_master0: reading STL from
/output/des02/sim_rtl/uc0/stl_des02/axi_master0.p1.stl

分析：
这个问题的原因看起来是栈保护发生了溢出造成的，有两种方法解决这个问题，
第一种是减小激励文件数量。
第二种是想办法扩大内存等等

supermanqc

尝试采用了第一种简单的方法，减少激励内容：
原始激励：文件axi_master0.p0.stl

修改的激励如下：
只保留“ 50:        (  4,INCR)bwr             0x7885a0 ndata                  size:4                              dacc  ”这一行，其他的都删掉，
重新运行仿真：
结果如下：【问题解决了】

给朕添碗饭

求教，第二种想办法扩大内存的方法有尝试吗，要怎么做呀

年轻的韭菜

有用第三方库吗，uvm和sc之间怎么通信的
