Why there is no sample time setting for HDL counter block ?

Hi,

I have done an implementation in sample down module, where I use HDL counter. But, the sample time in this block is cannot be configured due to which unnecessary delay registers are been assigned in the out put the code to match the down sampled.

No assignment

Unnecessary code (it is small part but it generate junck of this which is useless)

 always @(posedge clk or posedge reset)
      begin : delayMatch13_process
        if (reset == 1'b1) begin

Answer 1

[Kiran Kintali]

hi mohammed,

It looks like larget delay banalce registers are inserted in your design.

Can you look at the following document to get insights on how to avoid this? thanks.

[Mohammed Shameem Hussain]

Yes, I found an option to disable the delay balance register in hdl settings.

Thank you

Answer 2

[Bharath Venkataraman]

Unfortunately, it is not clear what the issue is. Can you provide a model and show where the hdl counter is? The registers in the code you show do not seem related to the hdl counter - are you saying these are coming because of delay matching?

[Mohammed Shameem Hussain]

Please find the model in the attachment.

This delayMatch is generated from the hdl coder. I have attached the code. Please code generated particular to neural network it has lot delaymatch register, which seems unnecessary. Because which quartus is not generating code as the registers are limited in number to be used on the hardware.

Please suggest me how to avoid it so that I can generate a project in quartus.

Furthermore, I found some information on delaymatch prifixed registers: https://de.mathworks.com/help/hdlcoder/examples/delay-balancing-and-validation-model-workflow-in-hdl-coder.html

Why does this required if enable signal is available ?
