PAR M1.3: baspl:291,292 - pullup could not be placed
Record #2720
Product Family: Software
Product Line: FPGA Implementation
Product Part: par
Product Version: 1.3.
Problem Title:
PAR M1.3: baspl:291,292 - pullup could not be placed
Problem Description:
Urgency: standard
General Description: PAR gives the following warnings and
errors on a design:
WARNING:baspl:291 - The PULLUP component "<instance_name>" could not be placed.
ERROR:baspl:292 - This is probably due either to lack of resources or to preference conflicts.
Solution 1:
This error can occur if the Pullup component is used
improperly. Pullups should only be used on Input Pads,
Open-Drain outputs, and 3-State Outputs. Pullups can not
be used to drive a logic 1 on other types of signals. To
drive a logic 1 on other signals, use the VCC symbol. For
more details about these and other components, please see
