M1: Concept HDL Direct gives "Error#171: Port exists in entity
declaration..."



Problem Description:
Keywords: concept, hdl direct, 171, entity, port

Urgency: standard

Reference: 16464
General Description:

When a PAD is added or removed from a Concept schematic with
HDL direct enabled, or if the signal names change between the
IPAD and IBUF or OPAD and OBUF, saving the design with HDL
Direct enabled may give the following error:

<output>
Error #171: Port exists in entity declaration but not
   on the schematic. The entity declaration may need to be
   updated. Port name: .......

Would you like to like to overwrite the entity declaration
   <path to vhdl.vhd> with a new entity declaration derived
   fromthis file schematic?[y/n]
</output>

Are you sure? [y/n]


Solution 1:

Simply type "y" in response to both questions.

This should really be a warning, and will always
occur when adding/deleting/changing external ports.
The problem has been reported to Cadence.
