#352 add parasitics extraction tables for gf180mcuD Issue created by proppy As discussed in #342 (comment), we need the magic parasitic extraction to account for the 11K variant. Looking at https://github.com/RTimothyEdwards/open_pdks/blob/master/gf180mcu/magic/gf180mcu.tech#L3658-L3659 it seems that
0P9
and
1P1
are currently assigned to the same resistance. @RTimothyEdwards is that the only place that needs "updating"? We were looking at the techlef in the 7t library with @msaligane, and it seems that both the
RESISTANCE
and
CAPACITANCE
and express in
PERSQ
units: https://github.com/google/globalfoundries-pdk-libs-gf180mcu_fd_sc_mcu7t5v0/blob/43beb45e4d323a76239de436db2df6732e9a689b/tech/gf180mcu_5LM_1TM_9K_7t_tech.lef#L275-L305 https://github.com/google/globalfoundries-pdk-libs-gf180mcu_fd_sc_mcu7t5v0/blob/43beb45e4d323a76239de436db2df6732e9a689b/tech/gf180mcu_5LM_1TM_11K_7t_tech.lef#L274-L304 Should we assume that the tools take into account the
THICKNESS
on top of this reference value in their calculation, or does that also need to be updated. RTimothyEdwards/open_pdks
