 Steps to run regression testing:

-2) Navigate to the compiler directory (trunk/compiler/tests)
+2) Navigate to the compiler directory: cd $OPENRAM_HOME
 3) Use the command: 
-   python regress.py 
+   python tests/regress.py -t freepdk45
 4) To run a specific test:
-   python {unit test}.py 
+   python tests/{unit test}.py -t freepdk45
 
 The unit tests take the same arguments as openram.py itself. 
 
 To increase the verbosity of the test, add one (or more) -v options:
-python tests/00_code_format_check_test.py -v
+python tests/00_code_format_check_test.py -v -t freepdk45
 
 To specify a particular technology use "-t <techname>" such as

+"-t scn3me_subm". 
 
 A regression daemon script that can be used with cron is included:
