RE: JEITA's comments and requests for SystemC and TLM-2.0

John,

About issue 1 (# reset_signal_is for an SC_THREAD), the latest revision of the Cadence process control spec submitted to the LWG on 8th May, 2009, supports multiple reset_signal_is() specification for a single thread (Section 2.8.3).

I understand the process control extensions are the next enhancement on your plate to review - are you looking at this latest version of the spec?

Thanks,
-Bishnupriya

Hiroshi-san,

Some remarks on the JEITA comments and requests:

SystemC
1. # of reset_signal_is for an SC_THREAD

        Answer: The SystemC LWG agreed some time ago to explicitly restrict the number of occurrences of reset_signal_is to 1-per-thread. Do you intend to raise an enhancement request for more than one reset signal per thread?


TLM-2.0
1. Insufficient explanation of hop

        Answer: The LRM will say "The entire path between an initiator and a target consists of a number of hops, each hop connecting two adjacent components. A hop consists of one initiator socket bound to one target socket. The number of hops from initiator to target is one less than the number of interconnect components on that path. When using the generic payload, the forward and backward paths should each pass through the same set of components and sockets in opposing directions."
        Is that clear?
        We will add cross-references to the TLM-2 glossary entries.

2. Insufficient explanation of ignorable phase.

        Answer: There is an entire clause (ex. 8.2.5) dedicated to ignorable phases, complete with examples. I would welcome your input on how this could be improved.

10. In "attribute", "artefacts" should be "artifacts".

        Answer: "artefact" and "artifact" are variant spellings of the same word. "artifact" is said to be British spelling, though as a native British-speaker, I would not notice or care :-)
