Record #4118

Product Family: Software

Product Line: FPGA Implementation

Product Part: bitgen

Product Version: 1.4.

Problem Title:
BITGEN M1.4: WARNING:x4kdr:23 - Blockcheck: The comp (mapped physical logic cell) "<comp_name>" does not have any pins that are being used.



Problem Description:
Urgency: Standard

General Description:


BITGEN: Xilinx Bitstream Generator M1.4.12

Running DRC.

WARNING:x4kdr:23 - Blockcheck: The comp (mapped physical logic cell) "<comp_name>" does not have any
  pins that are being used.


Solution 1:

This usually involves an output IOB driven by ground.
Because the ground source can be obtained internal to
the IOB, there are legitimately no pins used by the IOB
component. If a pad driven by ground is not the expected configuration, look for reasons why the rel evant logic is being optimised to ground.
