From e4875df4e5eda55414fe707f1a6ced96a4a83a30 Mon Sep 17 00:00:00 2001 From: Staf Verhaegen Date: Wed, 3 Jan 2018 21:54:38 +0000 Subject: Value of properties can be expression. Example found in the 2007.03 Liberty Reference Manual that was also found in the wild: input_voltage(CMOS) { vil : 0.3 * VDD ; vih : 0.7 * VDD ; vimin : -0.5 ; vimax : VDD + 0.5 ; } Current implementation just parses the expression but no interpretation is done. --- src/map/scl/sclLiberty.c | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'src') diff --git a/src/map/scl/sclLiberty.c b/src/map/scl/sclLiberty.c index b48cfbe1..fc06bc47 100644 --- a/src/map/scl/sclLiberty.c +++ b/src/map/scl/sclLiberty.c @@ -399,6 +399,18 @@ int Scl_LibertyBuildItem( Scl_Tree_t * p, char ** ppPos, char * pEnd ) if ( Scl_LibertySkipSpaces( p, ppPos, pEnd, 1 ) ) goto exit; pNext = *ppPos; + while ( *pNext == '+' || *pNext == '-' || *pNext == '*' || *pNext == '/' ) + { + (*ppPos) += 1; + if ( Scl_LibertySkipSpaces( p, ppPos, pEnd, 0 ) ) + goto exit; + if ( Scl_LibertySkipEntry( ppPos, pEnd ) ) + goto exit; + Head.End = *ppPos - p->pContents; + if ( Scl_LibertySkipSpaces( p, ppPos, pEnd, 1 ) ) + goto exit; + pNext = *ppPos; + } if ( *pNext != ';' && *pNext != '\n' ) goto exit; *ppPos = pNext + 1; -- cgit v1.2.3
