Here is some more general advice for simulation of HDL code. No respect is paid to verification methodologies like UVM or OSVVM. Most of it is obvious, but it helps my memory when I write these things down.

• Use one big record type to define what is part of a test case.
  Then define multiple constants of the test case record type, one for each test case.
  Scheduling of and switching between test cases becomes a matter of a single signal/variable assignment.
• Read test cases from a file. Switching between test cases becomes a matter of reading from an different file. Test cases can be run in sequence by reading several files in sequence. It’s now possible to add test cases into a version control system separately. A disadvantage is that additional coding and maintenance for the test case files is required.
• Write reusable procedures and functions to generate the stimuli for the DUT. This is a kind of primitive BFM.

An interesting read about a Git branching model. Not really a novel approach, however still a nice summary on how to use git in the 21st century. Does not point out how to avoid common pitfalls and misses to give some reasoning on why things should be done the way they are shown. Does include a link to a comparison between Git and SVN.

Here’s a suggested approach on how to grow your home sound system from a simple stereo system to a full grown 7.1/2 surround sound theater.

1. Start with a simple stereo system. 2 speakers, front left and front right.
2. Add a subwoofer for improved bass.
3. Add a center speaker.
4. Add 2 speakers, rear left and rear right. This makes a 5.1 system.
5. Add 2 speakers, effect left and effect right. This makes a 7.1 system.
6. Add another subwoofer. This makes a 7.2 system.
7. That’s it.

On the Spartan 3E Starter Board the signals A and B of the rotary shaft encoder are actually inverted!
This is not mentioned in the documentation, the figure found there is strongly misleading . At least the pullup resistors are mentioned, which can bring you on the right track.
Oh and remember to put a reset on your FSMs :o)

1- Unpack, burn or mount
2- Install the game
3- Copy the crack from PROPHET dir
4- Go To Hell!
