"""Convert the operand string to use ABI register naming.
At this stage in the conversion of the Ibex log to CSV format, the operand
string is in this format:
"x6,x6,1000".
This function converts the register names to their ABI equivalents as shown below:
"t1,t1,1000".
This step is needed for the RISCV-DV functional coverage step, as it assumes that
all operand registers already follow the ABI naming scheme.
Args:
operand_str : A string of the operands for a given instruction
Returns:
A string of the operands for the instruction, with register names converted to ABI.
