Interactive point-to-point resistance simulations simplify net segmentation for faster, easier debug of high resistance segments

Screenshots showing a visual display of a net divided into three segments, using the setup data for the segments entered in the Calibre interactive P2P GUI.
The Calibre interactive P2P GUI enables design teams to interactively set up and run coordinate-based Calibre PERC P2P simulation runs, making it an effective debug tool for rule-based P2P violations. Designers can quickly and easily place source and sink probe points in a layout, simplifying and speeding up net segmentation and targeted P2P simulations. This simple, fast, and effective solution provided by the Calibre RVE interactive P2P GUI gives IC designers the data they need to accurately reduce parasitic effective resistance while eliminating traditional time-consuming P2P simulation runs. The ease of use combined with the speed and accuracy of the results make the Calibre interactive P2P GUI an effective option for improving the productivity and ease of use of the IC reliability verification flow.

Interactive point-to-point resistance simulations speed up and simplify debug of resistance violations

Point to point (P2P) resistance simulations calculate the effective resistance of the layout traces between points on an IC net trace, and let the designer know that there may be too much parasitic resistance from a particular net trace that would affect the reliability or performance of the circuit. However, traditional P2P simulation runs are time-consuming, and often require multiple iterations. The Calibre interactive P2P GUI enables designers to quickly select and place additional probe points anywhere on a net to get resistance measurements for individual net segments, rather than trying to work with either the effective overall resistance or all the individual polygon data throughout a CD run. Designers can quickly and iteratively increase the resolution of the net segments until they locate the root cause of the high resistance.
