Hello, i have some problems.
in a microcontroller circuit, we use CPLD between the CPU bus and I/O Device bus.
we use reference design circuit, and we use xilinx xc9572xl-10 , instead of altera epm7064 - 7..
but our xilinx doesnt work, it works but not all functions..
can be any problem with the Time issue, cause altera is 7ns, our xilinx is 10 ns.
does it matter a lot?
we dont use any global clocks GCK or etc..
our inputs are IORD# IOWR# OE# WR# ... from CPU..
the problem is not very clearly, sorry, if you want i can attach the PLD circuit.
thank you.
