CNT0 clock source

In configuring CNT0 as counter, I have clock source options including CNT3 and Ext Clk from Matrix.

When I select Ext Clk from Matrix, CNT0 is automatically connected to CNT3.

What's going on here?  Makes no sense to have the matrix option and CNT3 option if they end up doing the same thing.

Hi David,

Hi David,

could you please share some screenshot or test design file with the issue? It works correct on my site, please see attached.

Thanks

Please try to use attached design example. Do you have the latest GPAK Designet software (6.18)?

Hi David,

Hi David,

did you try to run the test file I've sent last time? Does the issue still appear?

I will when I can.  I am trying to sort out some other issues, and this chip turned out to be too small for my application.

I noticed something that may help. Starting with the config in the 108_test file, CNT0 is set for Ext clock. If I apply CNT3 as the clock source, I get an orange connection to CNT3 output. If I then apply EXT Clk (from matrix) as the source for CNT0, the connection for CNT0's clock remains with CNT3's output but turns green.

When that connection is green, it can be moved or removed to connect it to a matrix point. Since the CNT0 output is a valid external connection, it is not automatically removed. Another way to clear this is to then select one of the CLK options as the source for the CNT0 clock, apply it, and then change the CNT0 clock source to be Ext Clk and apply that.

I'm using GP3 Designer ver 6.18 on a Mac.
