Description

  • Go through remaining errors and warnings in iDebug and review them with designers.
    • Preferably tune tool settings such that no waivers are needed.
    • Add waivers for remaining errors and warnings.
  • Remove ast_clks_byp from the list of black-boxed modules.
  • Analyze expressions that are currently black-boxed. Increase ri_max_total_range_bits if necessary, and ideally find a way to enable this on machines that have enough RAM.

Research direction

Start by reviewing the remaining errors and warnings in iDebug with the designers. Then inspect the black-boxed module list for ast_clks_byp and the expressions affected by ri_max_total_range_bits. Done means resolving or waiving all signoff issues, removing ast_clks_byp from black-boxing, and enabling broader range analysis where machine RAM permits.
