Top Three Progress

Last week’s

This week’s


Lookup rise time


Lookup fall time


Lookup propagation time


To do

  • Lookup: done

  • FPU: done

  • Calc:

    • Finish up the interconnects.

  • Top Three:

    • Finish up the interconnects.

    • Split the schematics and layout into parts for LVS


Questions/Concerns

  • Large block simulations take a long time

  • Getting top3 and calc to lvs before carnival!
