Ref: #293 Adjusted default mim cap device generator values to create DRC clean capacitors (both Magic with DRC full and Klayout). Please see new screen shots below.
The cell `sky130_fd_io__signal_5_sym_hv_local_5term` has a small metal resistor ring (donut shape) in the corner. This is apparently designed to cause the center of the shape to be an isolated net...
Specifically, this error shows up in the `top_power_lvc_wpad` and `top_ground_lvc_wpad`, which are the two pads with ground-to-ground back-to-back diodes. At issue is the DIODE layer covering the entire layout of...
Specifically, `sky130_ef_io__vssio_hvc_clamped_pad` and `sky130_ef_io__vddio_hvc_clamped_pad` need these. Four resistors total, two on either side of the connections between VSSIO and VSSIO_Q on the first pad, and between VDDIO and VDDIO_Q on...
As per [config.tcl](https://github.com/RTimothyEdwards/open_pdks/blob/master/gf180mcu/openlane/config.tcl) some of the file paths missing in the PDK directory. ``` # Latch mapping set ::env(SYNTH_LATCH_MAP) "$::env(PDK_ROOT)/$::env(PDK)/libs.tech/openlane/$::env(STD_CELL_LIBRARY)/latch_map.v" # Tri-state buffer mapping set ::env(TRISTATE_BUFFER_MAP) "$::env(PDK_ROOT)/$::env(PDK)/libs.tech/openlane/$::env(STD_CELL_LIBRARY)/tribuff_map.v" # Full adder...
# Issue - Device generator for mim caps creates DRC failing capacitors for both M3 and M4 caps. Please see screen shots below. # Desired Behavor - Device generator for...
magic extracts `area` and `pj` for diodes in all variants except `orig`. xschem models only netlist `area`; thus, `pj` is flagged as a missing parameter when using xschem generated schematics....
I installed the open_pdk using the procedures described but in the installation folder like /lib.tech folder in missing ngspice. Please look into it.
