addlosig(3) - Linux man page

Name

addlosig - create a logical signal

Synopsys

#include "mlo.h"
losig_list ∗addlosig(ptfig, index, namechain, type)
lofig_list ∗ptfig;
long index;
chain_list ∗namechain;
char type;

Parameters

ptfig

Pointer to the figure in which the signal should be added

index

Signal index

namechain

List of names of the signal

type

Signal type

Description

addlosig creates a new signal, and adds it to the list of signals pointed to by ptfig->LOSIG. The new signal is added in front of the list, and becomes itself the list head.
The type parameter can take two values :

EXTERNAL

The signal is attached to at least one connector of the figure.

INTERNAL

The signal is only attached to instance or transistor connector.

The index and type arguments fill the INDEX and TYPE fields of the losig(3) structure. The index is the signal identifier, so it should be unique at a given hierarchical level.
The namechain argument is a list of names, given in a chain_list. See chain(3) for details.

Return Value

addlosig returns a pointer to the newly created signal.

Errors

"∗∗∗ mbk error ∗∗∗ addlosig impossible signal index already exist in figure ptfig->NAME"

The index is already used in an other signal, and since it's the signal identifier, it can't be.

Example

#include "mlo.h"
losig_list ∗merge_and_create(pt, s0, s1) /∗ merge two signal in a third ∗/
lofig_list ∗pt;
losig_list ∗s0, ∗s1;
{
chain_list ∗c;
losig_list ∗s;
long max_index;

for (c = s0->NAMECHAIN; c; c = c->NEXT)

s1->NAMECHAIN = addchain(s1->NAMECHAIN, c);

/∗ find maximum index ∗/

for (s = pt->LOSIG; s; s = s->NEXT)

if (max_index < s->INDEX)

max_index = s->INDEX;

s = addlosig(pt, ++max_index, s1->NAMECHAIN,

s0->TYPE == EXTERNAL || s1->TYPE == EXTERNAL ?

EXTERNAL : INTERNAL);

dellosig(pt, s0);

dellosig(pt, s1);

return s;

}
