Does OpenSTA have any plans to support power analysis by reading SAIF files? #97

I noticed there is an example in the examples/ directory that demonstrates reading a VCD simulation file. I'm wondering if there are any plans to support reading SAIF files, and if so, when it might be available? |

It makes sense to support it. It is just another thing on an infinite list. I can't agree that it is easier to generate saif than vcd, since iverilog can produce vcd but not saif. I have a reader close to working I should be able to push later this week. |

I'm glad to hear that you have a nearly finished SAIF reader. I'm really looking forward to trying it out! |

I noticed that in the header of the provided gcd_sky130hd.saif file, there is a line (PROGRAM_NAME "vcd2saif.lisp"). Does this tool exist in OpenSTA? |

No. I tried using https://github.com/ZHANG-Qidi/VCD2SAIF/tree/main but it has a number of bugs so I gave up on it. |
