Is it possiable to arrive clock signal to spartan 2e, if I have already used all global clocks (device compromises 4 global clocks).
If I arrived input clock signal on I/O pin (not global) ISE 6.3.03 shows me following error: ERROR:Pack:1107 - Unable to combine the following symbols into a single GCLKIOB component: PAD symbol "CLK_1M" (Pad Signal = CLK_1M) GCLKIBUF symbol "clkDAC_bufg" (Output Signal = CLK_1M_BUF) Each of the following constraints specifies an illegal physical site for a component of type GCLKIOB: Symbol "CLK_1M" (LOC=P3) Please correct the constraints accordingly.
PLEASE HELP ME!
