From ffd6f571b531ae3725d7a4907573f027461493ce Mon Sep 17 00:00:00 2001 From: Jean-Paul Chaput Date: Sat, 12 Jun 2021 11:49:07 +0200 Subject: [PATCH] No longer connect the root of HTrees with straigh lines, use the router. * Change: In cumulus/plugins.chip.chip.doConnectCore(), do not use the feature of the HTree to connect the root buffer straight to the corona pin. It prevents the router to insert a diode when those wires are too long. So let the standard router manage them. Should add diode insertions in HTree.connectHTrees() later. --- cumulus/src/plugins/alpha/chip/chip.py | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/cumulus/src/plugins/alpha/chip/chip.py b/cumulus/src/plugins/alpha/chip/chip.py index 3bb2c033..6217296b 100644 --- a/cumulus/src/plugins/alpha/chip/chip.py +++ b/cumulus/src/plugins/alpha/chip/chip.py @@ -120,7 +120,7 @@ class Chip ( Block ): if self.conf.routingGauge.hasPowerSupply(): power = plugins.alpha.chip.powerplane.Builder( self.conf ) power.connectPower() - power.connectHTrees( self.hTrees ) + #power.connectHTrees( self.hTrees ) power.doLayout() Breakpoint.stop( 101, 'After Query power.' ) else:
