iVerilog 仿真器

通过 add_requires("iverilog") 配置，我们能够自动拉取 iverilog 工具链包，然后使用 set_toolchains("@iverilog") 自动绑定工具链来编译工程。

add_requires("iverilog") target("hello")  add_rules("iverilog.binary")  set_toolchains("@iverilog")  add_files("src/*.v")

设置抽象配置

add_requires("iverilog") target("hello")  add_rules("iverilog.binary")  set_toolchains("@iverilog")  add_files("src/*.v")  add_defines("TEST")  add_includedirs("inc")  set_languages("v1800-2009")

我们可以通过 set_languages("v1800-2009") 来设置切换 Verilog 的语言标准。

目前支持的一些取值和映射关系如下：

["v1364-1995"] = "-g1995" ["v1364-2001"] = "-g2001" ["v1364-2005"] = "-g2005" ["v1800-2005"] = "-g2005-sv" ["v1800-2009"] = "-g2009" ["v1800-2012"] = "-g2012"

设置自定义 flags

add_requires("iverilog") target("hello")  add_rules("iverilog.binary")  set_toolchains("@iverilog")  add_files("src/*.v")  add_values("iverilogs.flags", "-DTEST")

构建工程

$ xmake checking for iverilog ... iverilog checking for vvp ... vvp [ 50%]: linking.iverilog hello.vvp [100%]: build ok!

运行程序

$ xmake run hello world! LXT2 info: dumpfile hello.vcd opened for output. src/main.v:6: $finish called at 0 (1s)

Verilator 仿真器

通过 add_requires("verilator") 配置，我们能够自动拉取 verilator 工具链包，然后使用 set_toolchains("@verilator") 自动绑定到工具链来编译工程。

add_requires("verilator") target("hello")  add_rules("verilator.binary")  set_toolchains("@verilator")  add_files("src/*.v")  add_files("src/*.cpp")

verilator 工程，我们需要一个额外的 sim_main.cpp 文件参与编译，作为程序的入口代码。

#include "hello.h" #include "verilated.h"  int main(int argc, char** argv) {  VerilatedContext* contextp = new VerilatedContext;  contextp->commandArgs(argc, argv);  hello* top = new hello{contextp};  while (!contextp->gotFinish()) { top->eval(); }  delete top;  delete contextp;  return 0; }

设置抽象配置

add_requires("verilator") target("hello")  add_rules("verilator.binary")  set_toolchains("@verilator")  add_files("src/*.v")  add_defines("TEST")  add_includedirs("inc")  set_languages("v1800-2009")

我们可以通过 set_languages("v1800-2009") 来设置切换 Verilog 的语言标准。

目前支持的一些取值和映射关系如下：

-- Verilog ["v1364-1995"] = "+1364-1995ext+v", ["v1364-2001"] = "+1364-2001ext+v", ["v1364-2005"] = "+1364-2005ext+v", -- SystemVerilog ["v1800-2005"] = "+1800-2005ext+v", ["v1800-2009"] = "+1800-2009ext+v", ["v1800-2012"] = "+1800-2012ext+v", ["v1800-2017"] = "+1800-2017ext+v",

设置自定义 flags

add_requires("verilator") target("hello")  add_rules("verilator.binary")  set_toolchains("@verilator")  add_files("src/*.v")  add_files("src/*.cpp")  add_values("verilator.flags", "--trace", "--timing")

编译静态库

我们也提供了 verilator.static 规则来编译生成 verilator 静态库。

add_requires("verilator") target("hello")  add_rules("verilator.static")  set_toolchains("@verilator")  add_files("src/*.v")  target("test")  add_deps("hello")  add_files("src/*.cpp")
