HDF5 Trace Database

[sumit_tuwien]

Hello All,

I have a question.

If I want to create a signal tracing database which uses hdf5 format and add sc_hdf5_trace.*, how much approximate effort it will need? Does anybody have any estimation?

Regards,

Sumit

That depends on how much you can build on in terms of HDF5. I did a few implementations of some trace files (optimized VCD as well as FST, you can find them here: https://github.com/Minres/SystemC-Components/tree/develop/src/sysc/scc, e.g. fst_trace.hh or vcd_push_trace.hh). My guess would be around a week if you do not have to fiddle with the HDF5 format.

But as far as I can judge, HDF5 is not really good at storing trace data efficiently. You have to define a structure on top of HDF5 which takes some time to define efficiently....
