...

for the read and writes, I can do sequence

e.g. for read

{"t0":123, "t1":234, "t2":235, "t3":236, "n":"READ_TRANS", "n0":"BegReqE", "n1":"EndReqE", "n2":"rresp_t", "n3":"rresp_t_end"}

For signal:

{"t":123, "n":"r_valid, start", "MSG": "initial value"}
{"t":125, "n ":"r_valid, end", "MSG": "beginning of loop"}
{"t":125, "n":"r_valid, start"}

Ok?

should we name differently signals from different adapters? they will be in different files

This would be great to connect to logic analyzer hardware.
