Honored ContributorProblem with assigning clock
Hello,
I am using a Quartus II 14.0 software and SoCkit rev.C (with 5CSXFC6D6F31C8NES in it). I have a problem with assigning clock in my project. I want to make a simple project which will use slide buttons (as inputs), LEDs (outputs) and clock. First two of them are assigned properly (I have compliled a project without clock input and it was fine) but I have a huge problem in using clock. I want to use only one clock (treated as global) but I think I have an error in qsf file. --- Quote Start --- # --------------------------------------------------------------------------# ## Copyright (C) 1991-2014 Altera Corporation.

I have searched a few similar topics in forum but I haven't find answer. I also study an chapter from Quartus handbook but there are no instant formulas how to assign global clock (in qsf file) I think it's a basic error but I cannot find it/them. Sorry for my bad English. Thanks for your response. Michal
