如何为intel-modelsim加上已经编译好的uvm

lvzi2025-08-19 15:29

intel-modelsim不会像vcs那样自动编译uvm,需要手动编译编译的命令 gcc -fPIC -shared -o libuvm_dpi.so uvm_dpi.cc -I/home/zhoujie/intelFPGA/20.1/modelsim_ase/include/ -DQUESTA

含义： uvm_dpi.cc，这是入口，它通过include已经包括了dpi目录下所有文件 -I/home/zhoujie/intelFPGA/20.1/modelsim_ase/include/ 有些依赖在仿真器里，需要include -DQUESTA指定，因为在uvm_hdl.c里面，判断使用哪一个编译器，如果用modelsim,需要指定QUESTA

另外

ini 复制代码

uvm_common.c: In function 'm_uvm_report_dpi':
uvm_common.c:50:3: error: unknown type name 'svScope'
   50 |   svScope old_scope = svSetScope(svGetScopeFromName(uvm_package_scope_name));
      |   ^~~~~~~

uvm_common.c: In function 'int_str_max':

   57 |     int val = INT_MAX;
      |               ^~~~~~~
uvm_common.c:1:1: note: 'INT_MAX' is defined in header '<limits.h>'; did you forget to '#include <limits.h>'?
  +++ |+#include <limits.h>

这个虽然不知道为什么，但是就是缺

arduino 复制代码

#include <svdpi.h>
#include <limits.h>

在uvm_common.c加上即可

UVM版本

1800.2-2020

Merge pull request #18 from jrefice/official_release_3_1 · accellera-official/uvm-core@78c0654

坑2

刚刚编译的uvm是64位的，但是intel-modelsim是32位的，不匹配

需要编译32位的， gcc -m32 -fPIC -shared -o libuvm_dpi.so uvm_dpi.cc -I/home/zhoujie/intelFPGA/20.1/modelsim_ase/include/ -DQUESTA

缺一些依赖，根据gcc和g++版本装即可

sudo apt-get install gcc-11-multilib g++-11-multilib
