CONSTRAINTBDD(3) BDD functions CONSTRAINTBDD(3) ORIGIN This software belongs to the ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Université Pierre et Marie CURIE, in Paris, France. Web : http://asim.lip6.fr/recherche/alliance/ E-mail : alliance-users@asim.lip6.fr NAME constraintBdd - restricts a BDD to another BDD SYNOPSYS #include "logmmm.h" pNode constraintBdd(pBdd1,pBdd2) pNode pBdd1; pNode pBdd2; PARAMETERS pBdd1 BDD to restrict pBdd2 constraint BDD DESCRIPTION constraintBdd() constructs the graph for the function obtained by restricting pBdd1 on pBdd2. This function can be used for example when a primary input is stuck at 0 or 1. EXAMPLE #include "mutnnn.h" /* mbk utilities */ #include "logmmm.h" pNode nodeA,nodeB; pNode res; initializeBdd(SMALL_BDD); nodeA = createNodeTermBdd(3); nodeB = createNodeTermBdd(3); res = applyBinBdd(OR,nodeA,nodeB); /* res = (OR a b) res = constraintBdd(res,nodeA); /* a = 1 */ displayBdd(res,1); /* it will display @res ONE */ destroyBdd(1); SEE ALSO log(1), bdd(1), simplifDcOneBdd(3), simplifDcZeroBdd(3), composeBdd(3), applyBdd(3), notBdd(3), applyBinBdd(3), addListBdd(3), displayBdd(3), createNodeTermBdd(3).
