STA
  • The most important and time-consuming part is finding vectors that can sensitize the corresponding paths.
  • That problem is similar to the one in ATPG, but a little bit different. We should guarantee each side-input on the path behaves in a satisfactory manner.
  • When timing is involved, things become even more complex.
  • Is there any existing method that can easily identify false paths so that we can remove them beforehand? (… further studies)
multi core
Multi-core
  • Job division

* Finding paths–

Dividing POs to each processor and doing traversals respectively.

* Finding vectors–

Dividing paths to processors and running sensitization algorithm independently.

implementation
Implementation
  • Data structure

* Gate–

gate name, input pins, output pins, etc.

* Path–

slack, starting PI, ending PO, passing pins, etc.

  • Parser

Different from last time, the name of the pins and the name of each gate should be kept.

future work
Future Work
  • Winter vacation

* Finishing implementation of Parser

* 1st version STA program
