I am traying to sythetize my new custom IP in ISE project, but i have this error:
ERROR:Xst:2035 - Port <SPLB_Clk> has illegal connections. This port is connected to an input buffer and other components.
Port <I> of node <CLK_BUS_BUFGP> (BUFGP) in unit <USER_LOGIC_I/instance_asepa>
I tried differents issues explaining in this forum community, for exemple :
1. Right click on the XST process and select properites
2. Find the -sd setting
3. Browse to your XPS's implementation directory
4. Select OK
but i have always the same error...
I tried also Unchecking "Add I/O Buffers" , the systhetize-xst is passed, but not Implement design
Can anyone help me to fix this error please?
