PARAMETERS¶
- busname
- Common signal name for a bus
- from
- Starting index of the set of signal, from
included
- to
- Ending index of the set of signal, to included
DESCRIPTION¶
GENLIB_BUS Creates a set of names, based upon a common name, valid for
the genlib netlist functions that manipulate the signal, and/or connector,
concept. They are:
The
from, to arguments give the boundaries of the bus to be created, both
of them beeing included in the set. The function allows increasing or
decreasing order busses, as one could expect.
This function has a constant equivalent, it means that if the
from, to
values are known at compilation time, one should better use, for readability
purposes, the "[n:m]" construct.
EXAMPLE¶
#include <genlib.h>
main()
{
int b = 0;
int e = 12;
/∗ Create a figure to work on ∗/
GENLIB_DEF_LOFIG("mycell");
/∗ define interface ∗/
GENLIB_LOCON(GENLIB_BUS("i", b, e), INPUT, GENLIB_BUS("sig", b, e);
GENLIB_LOCON("o[2:0]", OUTPUT, "sigout[4:6]");
/∗ Place an instance ∗/
GENLIB_LOINS("model","instance", GENLIB_BUS("sig", e/2), "sigout[6]", EOL);
/∗ Save all that on disk ∗/
GENLIB_SAVE_LOFIG();
}
