E203的Makefile默认是调用 iverilog编译rtl，我们可以做如下修改，使其支持vcs编译。
1. 首先修改e200_opensource/tb/tb_top.v， 增加dump波形的两行代码，这样如果指定DUMPWAVE不等于0，就会打印dump出波形文件。
initial begin
$value$plusargs("DUMPWAVE=%d",dumpwave);
if(dumpwave != 0)begin
// To add your waveform generation function
$fsdbDumpfile("dump.fsdb");
$fsdbDumpvars("+all");
end
end
2.修改e200_opensource/vsim/bin/run.makefile, 把SIM_TOOL,SIM_OPTIONS,WAVE_TOOL,WAVE_OPTIONS这些选项为vcs和verdi

#
# Note:

# use other EDA tools which support the systemverilog, you should not add this macro "DISABLE_SV_ASSERTION".
#
# Here we didnt add macro "ENABLE_TB_FORCE"
# that macro was used to enable the random interrupt and bus-error insertion to make
# more intensive test in e200_opensource/tb/tb_top.v.
# Although the test become more intensive, the drawback is it makes the regression
# simulation running very slower, so by default now it is turned off.
# If you want to turn on them without caring the the regression speed,
# you can just add macro `ENABLE_TB_FORCE` here in command line.

3. cd e200_opensource/vsim, 执行make install CORE=e203,
执行make install，则会在e200_opensource/vsim目录下，创建install目录，并把testbench文件和rtl文件copy到install目录，并把testbench文件tb_top.v中的e200,替换为core_name,E200替换为CORE_NAME,也就是e203。

4. 在目录e200_opensource/vsim执行make compile
这是会执行以下的flow，会创建run目录，并链接run/Makefile到bin/run.makefile，这个时候执行make compile
${RUN_DIR}:
mkdir -p ${RUN_DIR}
rm -f ${RUN_DIR}/Makefile
ln -s ${SIM_DIR}/bin/run.makefile ${RUN_DIR}/Makefile
compile: ${RUN_DIR}
make compile RUN_DIR=${RUN_DIR} -C ${RUN_DIR}
就是在run目录下执行Makefile文件中的make all,编译rtl代码和testbench文件。
all: run
compile.flg: ${RTL_V_FILES} ${TB_V_FILES}
@-rm -rf compile.flg
${SIM_TOOL} ${SIM_OPTIONS} ${RTL_V_FILES} ${TB_V_FILES} ;
touch compile.flg
５. 在e200_opensource/vsim目录里下执行make run_test, 则会调用以下flow,默认会run testcase rv32ui-p-add
run_test: compile
make run DUMPWAVE=${DUMPWAVE} TESTCASE=${TESTCASE} RUN_DIR=${RUN_DIR} -C ${RUN_DIR}
cd ${TEST_RUNDIR}; ${SIM_EXEC} +DUMPWAVE=${DUMPWAVE} +TESTCASE=${TESTCASE} |& tee ${TESTNAME}.log; cd ${RUN_DIR};
此时run目录下会有rv32ui-p-add目录，里面会有波形文件和log文件。
６. 在e200_opensource/vsim目录里下执行 make run_test TESTNAME=rv32ui-p-and, 此时run目录下会有rv32ui-p-and目录，里面会有波形文件和log文件。
7. 在e200_opensource/vsim目录里下执行 make wave,则会在verdi中打开rtl文件，然后打开相应test的波形文件，就可以就行调试程序了。
８.我们对Makefile进行一点改动，用make debug TESTNAME=rv32ui-p-and 就可以同时打开design和波形了。
e200_opensource/vsim/Makefile, 增加debug部分。

９. 在e200_opensource/vsim目录里下执行make regress_run CORE=e203, 则会运行所有的testcase，进行回归测试。
10. 在e200_opensource/vsim目录里下执行make regress_collect CORE=e203, 则会比较所有的testcase结果，如果test pass，则打印PASS,失败，则打印FAIL
11. 在e200_opensource/vsim目录里下执行make clean, 则会删除install和run目录。
