Example risc_cpu from systemc-2.3.4.zip issues.

[djmoore]

Good Day,

I was using the example risc_cpu from systemc-2.3.4.zip  from your website.

I used the default file test.asm and the branch instruction [bne     R5, R6, -6] does not work.

I see what may be some type of issue with timing or handshake, etc.

I debugged some and see clear_branch(), and branch_valid() seem to be done and causing branch_target_address.write() to be done at the wrong time.

 

Do you have updated code that emulates the instructions correctly for systemc-2.3.4.zip or later codebase?

Thanks

Doug Moore

I suggest that you test whether this problem is present when building SystemC and the example from the official public Git repository and otherwise raise this issue/provide a PR on the GitHub issue tracker so that it gets seen by the people involved in the development of the proof-of-concept simulator.
