|Ranking Modelsim Coverage results using Python for Speed? ! |
| |
|I have a problem with ranking tests at work -it just takes too long |
|and the 'obvious algorithm' should be much quicker. |
| |
| |
|The Task |
|I should explain that we use modelsim for simulating a processor |
|described in Verilog RTL and create PSL assertions and cover |
|statements to help with the verification. Periodically we run coverage|
|simulations and create coverage databases for each test that contains |
|the coverage information for each PSL cover or assert statement. |
| |
|[..] |
| |
|The Problem |
| We have a problem however with the Modelsim 'vcover ranktest' command|
| that we use to perform the ranking. It takes around ten hours to rank|
| ~5000 tests when we were hoping for around one hour. |
| |

| |
|My program, is 120 lines of Python and took a minute to run! |
