Upgrade IP (t)error, when using two (different) instances of the LPM_compare

Honored Contributor II

For a circuit that includes two LPM_compare components generated by the MegaWizard, I suddenly get the ip upgrade required prompted. 

However, when I launch the IP Upgrade Tool, then only one of the instances are listed and I cannot resolve the error... 

There seems to be some bug, because this issue occurs only occasionally  


Any others experienced this ?

No matter how many instances of an IP you have, the IP upgrade tool will have to upgrade only the main IP component. This will reflect throughout the design where ever the same IP is instanced again. You may want to close and restart Quartus tool after the IP upgrade and check again.
