TLM 1.0 => TLM 2.0

[sarav]

Hello
There is an existing model with tlm1.0 sockets - sc_port and sc_export.

Is it possible to bind these sockets to tlm2.0 initiator and target sockets?

If yes, then what is the conversion procedure involved?

I'm new to SystemC, any help/insight on this is appreciated.

Thanks.

Hi.

AFAIK, there is nothing like that.

In TLM1 communication is based on fifos. In TLM2 it is sockets and transport calls. This is a big difference. TLM2 is conceptually different and not just a slight improvement over TLM1.

What you need is a channel that does the conversion from fifo content to payload and transport calls. This is not straightforward and not possible in a generic way.

Hello
Thank you for that information George.
I understand it is not as straightforward as binding sockets together.
Will it be possible to retrieve the data used in the fifo into a structure, and then mapping fields from that structure to appropriate fields in the tlm 2.0 payload?
Thanks

Yes, I do this kind of conversion of TLM-1.0 to TLM-2.0 and vice versa very often, because for synthesis only TLM-1.0 is supported, and for VP TLM-2.0 is commonly used.

The converter will be application-specific, because TLM-1.0 has no standard payload (Many TLM-1.0 models even define their own interfaces, instead of using standard put/get ).

TLM1.0 was just a methodology and not a standard like TLM2.0. So, either modify the existing model or write a transactor in which case it would be specific to the your TLM1.0 interface.
