Target Device : Max10 (10M50SAE144I7N)

Sampling Clock : 40Mhz
Required period : 5ms or over

i tried ram size maximum 128k @ 3ms under

so is there any way how to capture data over 1ms

No.  To capture more data in the existing buffer, use data qualification to store only the relevant samples.  For example, if signals don't transition for a number of clock cycles, there's no need to keep all of those data samples.  Use data qualification as essentially a write enable to the buffer.

I don't quite understand the issue. May I know what is the problem you are facing?


For best data acquisition, specify a global, non-gated clock that is synchronous to the signals under test.

Refer to the Timing Analysis section of the Compilation Report for the maximum frequency of the logic analyzer clock.

i wanna Capture Data for 10ms (@ posedge 40Mhz Clock)

 

but Signal Tap Sample depth maximum Setting is  128K.

 

at that time  data length  ≒ 2.87ms (≒ 3.28ms).

 

i wanna capture more long... is there any way capture depth more longer?
