AR# 14454: 4.2i PAR - WARNING:Par:69 - Option "-xe" overrides some effects of "-ol".
4.2i PAR - WARNING:Par:69 - Option "-xe" overrides some effects of "-ol".
Keywords: 4.2, WARNING, PAR, 69, Option, xe, overrides, ol
General Description: When I run PAR implementation, the following warning is often reported:
"WARNING:Par:69 - Option '-xe' overrides some effects of '-ol'"
This warning is normal and appears often when PAR is run. It occurs any time the extra effort option "-xe" is set to a value other than "0". As the default value for extra effort is "1", this message may appear without explicit use of this feature. The intention is to notify the user that the regular effort level option "-ol" will be affected by the use of the extra effort level option. This only occurs on higher -ol settings of 3-5.
To change the extra effort level:
- Go to Edit -> Preferences. - Select the Processes tab, set the Process Settings to "Advanced". - Right-click on "Implement Design", then select "Properties". - Select the Place and Route Properties tab and set the Extra Effort property as needed.
