Re: VHDL coding question
This is not an irreversible accident, just syntactic error =) Point is that I wrote this code in Quick Reply window. Moreover, it was in the small hours...
VHDL coding question
I'm using Quartus 6.0. And neither during compilation nor simulation there are no errors or warnings. Your project is functioning correctly. IF operator in VHDL is sequential operator, and therefore you have to use it only inside the PROCESS operator. The synthesiser based...
VHDL coding question
What kind of problems during simulation do you mean? This project is compiled without any warnings. RTL View shows that no latches were generated.
1. I don't know what is there with Virtex2Pro, but always VREF pins is needed only for voltage-referenced IO standards (for example SSTL). For example in Cyclone devices you can leave these pins unconnected (or user-defined) if you use single-ended IO standards (LVTTL, etc...). But in Stratix...
