• XilinxISE 10.1 "Undefined" problem on test wave bench
    0 replies, posted
Hey guys, I don't know if this is the right place to do it, but I have an assignment to present next friday and I've been having issues with Xilinx 10.1. Now before you say anything about the outdated version, yes, it's the version we use at university and therefore it's the version I use too. So I've been making a multiplier in Digital Systems. We have a 2 bit A variable which will represent the number we want to successively sum (multiplicate) and a 3 bit B input which is the number we want to sum A B times. Then for outputs we have 6 bit C which is the result, a stop output and a OK output. Stop means the end of each sum and OK means the operation is complete. Problem is when testing the functionality of the design in the test wave bench, some outputs of the C variable present themselves in a red line with a U for "undefined". This is really driving me crazy since I have to program a CPLD board with this and it won't let me with this error. If this information is not enough I can post my work and work objectives so you can help me further. Either way, does anyone have any idea of what this is? Thank You! PS - If someone does get to help me, I will mention him on my assignment's report!
