RE: [oc] FPGA constraint problem

You don;t have to use only GCLKIO, you can also use regular IO.

look on the msg Xilinx tell you it will also give you a way to "solve" the
problem of feeding a GCLK from any IO.

it is a line you need to add to your environment.

have a nice day

Subject: [oc] FPGA constraint problem




I'm currently trying test my I2C .vhd project.  But, when I tried to do 
the contraints on my spartan2 fpga.  it gives me error that I have to use
SCL as GCLKIOB.  

Do I really need to tie the SCL pin to one of the GCK?

Can I contrains the SCL to any other port?
