2.1i COREGEN, C_IP4: "FATAL: RPM arrangement for a1/RAM_0/BIT_1 cannot be placed in RPM arrangement for a1/RAM_0 due to resource contention." for RAM-Based Shift Register
the core will fail in CORE Generator with the following error message:
FATAL: RPM arrangement for a1/RAM_0/BIT_1 cannot be placed in RPM arrangement for a1/RAM_0 due to resource contention. ERROR: An internal error has occurred. Please call Xilinx support. FATAL: Cannot place row template arrangement for a1 because resource assignment is not complete. ERROR: An internal error has occurred. Please call Xilinx support. WARNING: Core a1 did not generate product ImpNetlist. Debug: Implementation netlist failed!! ERROR: Errors encountered while generating a1 (RAM-based_Shift_Register 1.0). No output files have been generated.
Solution
To work around this problem, try disabling the "Create RPM" option. The drawback is that performance may deteriorate to a certain extent.
