From f288c4d7f6e97146bdc4de48f14168cbce9d3c96 Mon Sep 17 00:00:00 2001 From: QuantamHD Date: Mon, 20 Dec 2021 12:55:11 -0800 Subject: Fixes internal pin parsing error in ASAP7 liberty file. This fix addresses an issue I saw with the ASAP7 liberty files and ABC. ASAP7 lists internal pins in its liberty file which ABC's liberty parser doesn't account for. This causes an assert to be triggered. This fix simply adds interal pins to the ignore list. --- src/map/scl/sclLiberty.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'src/map') diff --git a/src/map/scl/sclLiberty.c b/src/map/scl/sclLiberty.c index 4b6adab4..49b5c237 100644 --- a/src/map/scl/sclLiberty.c +++ b/src/map/scl/sclLiberty.c @@ -955,6 +955,8 @@ int Scl_LibertyReadPinDirection( Scl_Tree_t * p, Scl_Item_t * pPin ) return 0; if ( !strcmp(pToken, "output") ) return 1; + if ( !strcmp(pToken, "internal") ) + return 2; break; } return -1; @@ -1525,7 +1527,7 @@ Vec_Str_t * Scl_LibertyReadSclStr( Scl_Tree_t * p, int fVerbose, int fVeryVerbos float CapOne, CapRise, CapFall; if ( Scl_LibertyReadPinFormula(p, pPin) != NULL ) // skip output pin continue; - assert( Scl_LibertyReadPinDirection(p, pPin) == 0 ); + assert( Scl_LibertyReadPinDirection(p, pPin) == 0 || Scl_LibertyReadPinDirection(p, pPin) == 2); pName = Scl_LibertyReadString(p, pPin->Head); Vec_PtrPush( vNameIns, Abc_UtilStrsav(pName) ); Vec_StrPutS_( vOut, pName ); @@ -1546,6 +1548,8 @@ Vec_Str_t * Scl_LibertyReadSclStr( Scl_Tree_t * p, int fVerbose, int fVeryVerbos { if ( !Scl_LibertyReadPinFormula(p, pPin) ) // skip input pin continue; + if (Scl_LibertyReadPinDirection(p, pPin) == 2) // skip internal pin + continue; assert( Scl_LibertyReadPinDirection(p, pPin) == 1 ); pName = Scl_LibertyReadString(p, pPin->Head); Vec_StrPutS_( vOut, pName ); -- cgit v1.2.3
