fst waveform analyzing for imatmul program

[Tanishqgithub]

@mp-17

I have successfully generated the .fst file for the imatmul program, and I need assistance in analyzing the corresponding waveform.

From my understanding, the assembly-level program (ISA) is generated in ara/apps/bin/imatmul.dump Could you please provide guidance on the following aspects of the waveform analysis:

1. Vector Instruction Issuance to ARA Vector Co-Processor:
   I’m trying to identify the signal in the waveform that shows the moment when vector instructions are issued from the Ariane core to the ARA Vector Co-Processor. Specifically, I’m looking for the signal that confirms when Ariane understands that the instruction is a vector instruction and passes it on to the vector unit for processing.

2. Multiplication Operation in simd_mul.sv:
   I’m also trying to locate where the actual multiplication of operands occurs, particularly in the simd_mul unit. I would appreciate help identifying the signals or patterns that correspond to the SIMD multiplication operation in the waveform.

Any detailed guidance on how to effectively analyze these aspects within the waveform would be highly appreciated.

Thanks in advance for your support!
