running 2 cross dependancy tests:

archive

hello, i'd like to make an inout file interface between 2 dut's that feeding each other with data (to imitate the operation of socket). therefore, each dut test process reads data from one file and writes data to another, whereas the other dut, does the same only with opposite files. my question is whether specman can deal reading and writing to/from the same file on the same time without causing deadlock. should i use some sort of mutex to avoid the situation when one dut test process open a file for reading, but there's nothing to read, while the other process cannot write data to this file since it's already opened for reading by another process. perhaps you have a better solution without using files ? thanks, Zohar

  • - What is the physical interface (e.g. data-bus/Ethernet/USB etc.) between these two DUTs?

    A: my file interface is simulating data-bus

    - What type of data is exchanged on this interface (e.g. data read/write transactions or data-packets)?

    A: data RW transtactions (bus length is 40bits, and i split it to 4 data lines length 10 bits each)

    - How is your simulation set up? Are the DUT models in HDL or SystemC or e? What is the implementation of the "dut test process" for each DUT? An HDL or SystemC process? A TCM in e?

    A: i'm working on specman (e) environment, and that's the impementation of each dut test process.


    i'd like to denote that both dut test processes are running seperately on the same time (not necessarily on the same machine) and the file is the only connection between them. i'm wondering if there's a better solution than my current usage of files.

    i hope i manage to clarify things ...
    thanks for the help !!!
