Subject: [oc] VHDL bus cycle implementation for wishbone/opencores
Hi,I'm curious to know in what fashion bus cycles should be implemented in VHDL, specifically using the WISHBONE bus system.
Describing these cycles behaviorally (wait statements) seems to be the logical solution, however the code would not be synthesizable (or would it be with newer tools?, if so which ones?).
Likewise, how would one deal with timing issues (setup time/hold time) when dealing with this problem.
Is the solution to these above two problems simply to write tedious state machines (mealy or moore?) and counters (for the timing), or is there hopefully a more efficient way?
Can anyone suggest some references?
Thanks in advance!
Edmond
