pylab_ml.common.file_io.readVlogMemFile

readVlogMemFile(fileName, memSize=0, defaultvalues=None, bitwidth=None, debug=False)

Read a file with memory data in verilog hex format.

eg. readVlogMemFile(‘memory.v’) will read the memory data from the file ‘memory.v’ in verilog hex format and return the starting address and a list of memory data.

The function will read the file line by line, parse the address and data values in verilog hex format, and fill a list with the memory data. The function will also determine the memory size and bit width from the data in the file if memSize and bitwidth parameters are not provided.

Parameters:

• fileName (string) – The name of the verilog file containing memory data.

• memSize (int) – The number of memory addresses. If 0, the size will be calculated from the data in the file.

• defaultvalues (int) – The default values for the memory array if no data is read.

• bitwidth (int) – The bit width of the data.

• debug (bool) – If True, it prints out the data loaded.

Returns:

• int – startadr : The starting address of the memory data.

• list – data : A list of memory data, with None entries for unused/initialized values.
