#371 Varactor generated by Magic has DRC error Issue created by simonwaid Creating a N-Type Varactor with multiple fingers causes the DRC error "N-Well overlap of varactor poly < 0.15um (varac.5)". The error is only visible when descending into the Varactor cell. Steps to reproduce In Magic do the following: • Create the Varactor: • Devices 1 -> MOS Varactor • Width= 4, Lenght=10, Fingers=5, M=5 • Create and close • Descend into the Varactor Cell • Options -> Cell Manager • Select the Varactor Cell, press Load • Perform a DRC: • DRC -> DRC Complete • Options -> DRC Manager The DRC Manager will show the error: N-Well overlap of varactor poly < 0.15um (varac.5) RTimothyEdwards/open_pdks

			../scripts/download.sh ${PDK_LIB_PR} ${GF180MCU_PR_PATH} ${FD_PR_COMMIT}; \
		fi ; \
	fi

This wouldn't work.

FD_PR_COMMIT = <>

is illegal sh syntax. It should be

FD_PR_COMMIT=<>

. The other issue is that

${FD_PR_COMMIT}

, in later lines, references the Make variable called

FD_PR_COMMIT

not the shell variable being created at runtime. RTimothyEdwards/open_pdks

#375 DRC errors on analog pad provided as part of the SKY130 pdk Issue created by simonwaid The analog pad (as well as other pads) provided as part of the skywater 130 pdk contains DRC errors Steps to repoduce: • Install magic rev. 8.3.399 • Install the skywater pdk using open_pdks rev. 1.0.414 to the default location • Copy /usr/local/share/pdk/sky130A/libs.tech/magic/sky130A.magicrc to your working directors and rename it to .magicrc • Open the analog pad using magic

magic /usr/local/share/pdk/sky130A/libs.ref/sky130_fd_io/mag/sky130_ef_io__analog_pad.mag

• Create a Box around the pad, press "a" followed by "x" to expand everything. • Drc -> DRC Complete • Drc -> DRC Update • Options -> DRC Manager shows "mcon spacing <0.19um" and "Metal5 overlap of via4" Similar issues are present also in other pads, such as sky130_ef_io__vccd_lvc_clamped3_pad.mag RTimothyEdwards/open_pdks
