用Systemverilog做验证项目实例

layout: fixed; margin-left: 1px; ">

接触了一下systemverilog，还是第一次，把自己的整个接触过程记录一下。梳理清楚一些关键的要点。
我们的systemverilog验证是一个印度哥们给做的，有几年经验了。
作为使用的初体验，首先是运行仿真，很简单，就是make 一下而已。
比如：
gmake my_test
当然，懂点Linux知识的都知道，执行这个命令的当前目录下，必须有形如Makefile之类的文件。该文件里面记录了需要做的实际工作。
好吧，让我们来看看这个Makefile。

Makefile的前言说明

这个Makefile是synopsys提供的模板，看上去非常好用，你只要按部就班提供实际项目的参数就可以了。我们来看这个文件的头部说明：

# Filename : $Id: Makefile,v 1.0 2006/07/18 23:59:59 vangundy Exp $
#
# Created by  : Synopsys Inc. 07/17/2006
#             $Author: vangundy $
#
# Description : Demonstrates Verilog DUT and SVTB using VCS
#
#  The Makefile works on two seperate flows.  The DEBUG flow is intended to be used
#  during debugging of a testcase and/or the DUT.  The REGRESSION flow is used
#  during regression runs and collects coverage data.
#
#  The DEBUG flow turns on VPD dumping and turns off coverage collection.  After
#  building a testcase using the debug targets, you can debug the TB and the DUT
#  source code using the testbench debugger and DVE.  Of course, you can turn on
#  coverage metrics and run in debug mode by changing compile and runtime options
#  in the makefile.  These changes are independent of the regression flow so that
#  the regressions will still run optimally without the interference of VPD
#  dumping.
#
#  The REGRESSION flow turns off VPD dumping and turns on Coverage Metrics and TB
#  coverage collection.  This flow is intended to support verification engineers who
#  are working through the regression process and are interested in coverage
#  collection and urg.
#
#  Command Line
#  ------------
#  The Makefile supports the following command line
#
#  % make target_name_* <SEED=xxx> <DEFINES=xxxx>
#
#  Where target_name is the name of a testcase located in the test directory.  Every
#  test in the test directory is named using test_{test_name}.  All of the test targets
#  are listed in the TEST TARGETS section of the makefile.
#
#  Compile and Run Testcases
#  -------------------------
#  To compile and run a tescase use the test_* and regress_test_* targets.
#
#  % make test_1          // Builds and runs test 1 with VPD dumping and debug on
#  % make regress_test_1 // Builds and runs test 1 with coverage turned on
#
#  Debugging Testcases
#  -------------------
#  You can use DVE and the testbench debugger to visualize waveforms and testbench
#  execution.  You must first build the testbench using the make compile_* command.
#
#  % make compile_1       // Builds test 1 for debugging
#
#  Once you have built the environment with the proper debug switches, you can use DVE
#  and the testbench debugger.
#
#  % make gui_1          // Debug test 1 with DVE
#  % make tb_gui_1       // Debug test 1 with the testbench debugger
#  % make both_guis_1    // Debug using both guis
#  % make pp_1          // Debug using the VPD file
#
#  If you want, you can turn on coverage for the DEBUG flow by uncommenting the
#  coverage flag in the makefile.  If you do this, you can still look at coverage.
#  This may be useful in helping those who are debugging coverage related issues.
#
#  % make urg             // Visualize coverage data from debug runs
#
#  Regression Testcases
#  --------------------
#  Regression tests are used to collect coverage information.  To build a testcase
#  for coverage collection use a command similar to the following.
#
#  % make regress_build_1  // Build and run a regression test with a default seed
#  Once the test has been built, you can run it again with a new seed.
#
#  % make regress_run_1 SEED=1234
#
#  After running one or more regression runs, you can visualize the coverage data
#  using urg and the following command
#
#  % make regress_urg
#-----------------------------------------------------------------------------

#-----------------------------------------------------------------------------
#
# HOW TO REUSE THIS FILE ON ANOTHER DUT
#
# STEP 1:  Update the file locations as required
# STEP 2:  Update the DUT section with directory and source location info
# STEP 3:  Update the TB section with directory and source location info
# STEP 4:  Update the Coverage section with name of dut top (eg top.dut)
# STEP 5:  Add test targets to the debug and regression targets section
# STEP 5:  Adjust the debug and regression compile and run time arguments
# STEP 7:  Adjust command line options as required
# STEP 8:  Update the env class so that it extends dkm_env
#    You will need to have a copy of the dkm directory and it should
#       be located at $(TB_SRC_DIR)/dkm
#       a) Add [`include "dkm_env.sv"]
#       b) Add [extends dkm_env] to the environment class definition
#          c) Call the super.new("name") from the constructor
# STEP 9:  Run the debug and regression targets
#          % make testbench_target_*
#
