- Are there public domain VHDL compilers?
-
- When I'm hacking out a new bus protocol, I usually use a tiny C package I
- wrote that inputs and outputs activities on nodes in a "Logio" format that
- looks something like this:
-
- Sequence: D Flip Flop
- Time: 0.0
- D: 0
- !RST: 1
- CLK: 0
- Time: 1.0
- CLK: 1
- Time: 1.1
- Q: 0
- !Q: 1
- Time: 2.0
- CLK: 0
- D: 1
- Time: 3.0
- CLK: 1
- Time: 3.1
- Q: 1
- !Q: 0
-
- ... and so on. This format is easy to display and debug with a simple
- text-based display program. Thus I can throw together stuff no matter
- where I am, without resorting to a pencil (which I don't remember how to
- use) and in spite of the fact that I'm too poor to buy a CAD tool. But I
- do wish that I could use VHDL instead of C.
-
- Does anything like this exist?
