multiports and indexed binding


Recommended Posts


In SystemC multi-ports, one could access the sc_interface methods of specific port instance using operator [] overloaded method. Was there any reason to not have had C++ method in sc_port to allow access to individual port instances?

For example,

Assume I have a port declaration like. sc_port<some_interface_type, 4> p;

I have to ensure the bind order so that the ports are bound correctly. For example,





Assume that we introduce a method named at(int index) in sc_port, that returns the sc_port instance for the index, then one could have performed bindings as follows (essentially, the order of binding is no more significant).





I have some of the binds captured in meta-data format( IPXACT) and my parser would not always return the bind in the sequence that the current SystemC expects. Having a _at_ method would have helped.

Any thoughts/suggestions/comments?

I don't know if there was a fundamental reason, but as multi-ports can be bound to an unknown number of interfaces (if you set max number of bindings to zero) maybe that's why? When you refer to "port instances" that's not what happens. There's only one port, with bindings to multiple interfaces.

If you want that feature, why not just use an array of ports, then you really will have multiple port instances?
