From 47df1178431cb04f57eb6600e64750ae2a7b6364 Mon Sep 17 00:00:00 2001 From: Tim Edwards Date: Sun, 11 Aug 2024 21:23:03 -0400 Subject: [PATCH] Modified the GDS read-in section of the magic tech file for sky130 to remove the area of any actual metal coincident with the corresponding fill block type from the fill block area. Otherwise the fill block will overwrite and obliterate the metal on read-in. This solves the issue reported on the github issue tracker for magic (issue 321). NOTE: There remains an issue that the "fillblock" layer in magic does not symmetrically write out and read back in; however, this problem is due mostly to the poor implementation of "fillblock". --- VERSION | 2 +- sky130/magic/sky130.tech | 12 +++++++++++- 2 files changed, 12 insertions(+), 2 deletions(-) diff --git a/VERSION b/VERSION index 3ba51343..b9c0a675 100644 --- a/VERSION +++ b/VERSION @@ -1 +1 @@ -1.0.491 +1.0.492 diff --git a/sky130/magic/sky130.tech b/sky130/magic/sky130.tech index 82c8cbc7..147f5020 100644 --- a/sky130/magic/sky130.tech +++ b/sky130/magic/sky130.tech @@ -3957,22 +3957,32 @@ style sky130 variants (),(vendor) # and FILLOBSM1,FILLOBSM2,FILLOBSM3,FILLOBSM4 # Use the obstruction types for fill block on individual layers - layer obsactive FILLOBSFOM,FILLOBSPOLY + templayer obspoly FILLOBSPOLY + and-not POLY + + layer obsactive FILLOBSFOM + and-not DIFF,TAP + or obspoly labels FILLOBSFOM,FILLOBSPOLY layer obsm1 FILLOBSM1 + and-not MET1 labels FILLOBSM1 layer obsm2 FILLOBSM2 + and-not MET2 labels FILLOBSM2 layer obsm3 FILLOBSM3 + and-not MET3 labels FILLOBSM3 layer obsm4 FILLOBSM4 + and-not MET4 labels FILLOBSM4 layer obsm5 FILLOBSM5 + and-not MET5 labels FILLOBSM5 # MOS Varactor
