I would like to use an DCM in a Xilinx Spartan 3E device. The synthesis is done with Mentor Graphics Precision. So I created a verilog file with verilog, but when I run synthesis, I get the error message:
# Error: : Unable to resolve reference to an Instance: DCM_SP_INST of Cell work.DCM_SP. # Error: Found unresolved black-boxes in the design, please fix the previous error messages before continuing
It seems to me that Precision does not recognize Xilinx' DCM for Spartan devices.
Do You have any ideas?
