如何的快速的搭建UVM环境呢，最好是一键式的创建，User只填空式的修改部分文件即可；基于这样的设想，开发了Auto Env的脚本；
1 ENV的目录结构
>-|--build.setup
|--sim
| |--makefile
| |--synopsys_sim.setup
| |--dut.f
| |--filelist.f
|
|--rtl
| |--xxx.v
|
|--tb
|--hdl
| |--xxx_top_tb.sv
| |--xxx_package.sv
|
|--env
| |--xxx_env.sv
| |--xxx_vsqr.sv
| |--xxx_rm.sv
| |--xxx_scoreboard.sv
|
|--yyy_agent
| |--yyy_if.sv
| |--yyy_transaction.sv
| |--yyy_driver.sv
| |--yyy_monitor.sv
| |--yyy_sequencer.sv
| |--yyy_agent.sv
|
|--cfg_agent
| |--cfg_if.sv
| |--cfg_transaction.sv
| |--//cfg_monitor.sv
| |--cfg_driver.sv
| |--cfg_sequencer.sv
| |--cfg_agent.sv
|
|--reg_model
| |--xxx_reg_blk.sv
| |--xxx_adapter.sv
|
|--testcase
|--xxx_base_vsqs.sv
|--xxx_base_case.sv
|--xxx_seqlib.f
|--xxx_caselib.f
从最顶层讲起：
-
build.setup：环境变量设置，要进入这个路径下，然后source build.setup；
-
剩下有3个目录，tb，rtl，sim：
-
rtl：将RTL代码放进去
-
sim：运行环境的地方
-
tb：环境主体
- 默认加入一个cfg_agent（控制通路，agent）
- 默认加入一个yyy_agent（数据通路，agent）
- 默认加入一个reg_model（寄存器模型）
- hdl顶层放入test_top和package
- 默认建立一个base的sequence和testcase
- env目录下放整个环境的env和package，还放整个环境的scoreboard和reference model
-
xxx前缀为整个系统的名称；
yyy为数据通路的前缀；
本文以带rgmii口的MAC为例，构建一个auto_env的python类，这个类包含了很多成员和方法，
- 可以满足一键式的建立UVM环境；
- 也可满足后续调用类中的过程，只产生一些agent；
2 本文模板
此部分主要产生各个文件的模板，便于后面class的调用；
2.1 sim路径下的文档模板
sim路径下的主要文件为makefile，其模板如下：
def mk_f(in_lst):
return '''dirs := %s tb
DUT_TOP := %s
TB_TOP := %s_top_tb
CASE := %s_base_case
clean:
rm -rf simv* csrc* ${VER_PATH}/libs *.log ucli.key vhdlanLog verdiLog *.fsdb novas.rc novas.conf profileReport* simprofile_dir vdCovLog vc_hdrs.h .vlogansetup.args partitionlib vhdl_objs_dir mkdir
$(foreach i, $(dirs), mkdir -p ${VER_PATH}/libs/$i)
ana:
vlogan -l dut.log -sverilog -kdb -work $(DUT_TOP) -f dut.f
vlogan -l uvm.log -sverilog -kdb -work tb -ntb_opts uvm
vlogan -l tb.log -sverilog -kdb -work tb -ntb_opts uvm -f filelist.f
comp:

3.1 函数简介
主要包括2部分内容：
- xxx_dir_gen：产生路径；
- top_dir_gen：产生最顶层的文件夹和文件；
- env_dir_gen：产生tb下除了agent之外的其他文件夹；
- agent_dir_gen：产生agent文件夹
- xxx_dec：根据模板产生代码；
- sim_dec：生成makefile，filelist.f，dut.f，synopsys_sim.setup
- agent_dec: 选择产生driver，monitor，iterface，transaction，sequencer，agent代码
- 如果cfg=1则，不产生monitor
- env_dec：生成vsequenser，model，scoreboard，env
- hdl_dec：生成package和top_tb
- case_dec：生成sequence和testcase以及sequencelib和testcaselib
- rm_dec：生成adapter和blk file
- blk_file为空文件，可用json2sv脚本直接产生sv文档；
- new_env：直接产生完整的验证环境；
