mo-hosni e076718887 add `/// sta-blackbox` in the modules that will be blackboxed in STA 2023-05-22 05:52:27 -07:00
mo-hosni 6b5aa27297 harden `housekeeping_alt` that will be integrated in `caravan_core` 2023-05-22 05:38:41 -07:00
mo-hosni 5339ed15b6 Merge branch 'caravan-mpw9-PnR' of github.com:efabless/caravel into caravan-mpw9-PnR 2023-05-22 02:34:33 -07:00
mo-hosni 4086fb7130 add PnR empty macros to act as placement obstructions 2023-05-22 02:33:57 -07:00
Tim Edwards e2cc50bae3 Copied housekeeping.v to housekeeping_alt.v and extended the 
function for clock routing to include GPIO[30] and GPIO[31], for
use with the caravan chip, which does not have GPIO in locations
14 and 15.  This restores the clock monitoring capability for
caravan.  Eventually, the housekeeping_alt module should become
the only housekeeping module, extending the clock monitoring
function for caravel and allowing the same module to be used for
both caravel and caravan.
