- We're about to plunk down $$$ for a logic synthesis package.
- I just finished reading "The VHDL Cookbook", and noticed that
- its RTL level example description of the 32 bit CPU "DP32" contained lots
- of wait statements inside processes (figure 7-26). The waits are
- usually of the form
- wait until phi1 = '1';
-
- I seem to recall that synthesis vendor X's software places big
- restrictions on where wait statements can occur.
- Can *any* synthesis tools handle the DP32 example?
- I'd like to fill in (and expand) the following table:
- vendor avail? DP32?
- Mentor now ?
- Synopsis now ?
- Exemplar now ?
- Cadence (1Q93) ?
- Instant Logic (1Q93) ?
-
- If you can help, please send me e-mail; I'll summarize.
- Thanks! (And thanks to Peter Ashenden for his great intro to VHDL!)
