GENLIB_REVERSE_PHCON.3(October 1, 1997) 								   GENLIB_REVERSE_PHCON.3(October 1, 1997)

NAME
GENLIB_REVERSE_PHCON - reverse the order of physical connectors on a bus. SYNOPSYS
#include <genlib.h> void GENLIB_REVERSE_PHCON(basename) char *basename; ORIGIN
This software belongs to the ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in Paris, France. Web : http://asim.lip6.fr/recherche/alliance/ E-mail : alliance-users@asim.lip6.fr PARAMETERS
basename Radical of the vector to be reversed. DESCRIPTION
REVERSE_PHCON will change the indexes of the vector called basename, making the greatest values the smallest and so on. Both hard connec- tors, created by PHCON(3) like functions and virtual ones, done with PHREF(3), will be taken into account for the reverse operation. This function is mainly useful to implement the msb0 options of the Alliance CAD system module generators, as the whole design can be done with the designer choosen bit ordering, and modified on user demand only before saving. EXAMPLE
#include <genlib.h> main() { GENLIB_DEF_PHFIG("rom"); /* Create a figure to work on */ . . . /* Reverse the bit ordering if needed */ if (msb0) GENLIB_REVERSE_PHCON("adr"); /* Save all that on disk */ GENLIB_SAVE_PHFIG(); } SEE ALSO
