How to configure more than 64 probes in VIO and ILA

Dear Sir/Ma'am,

In my design, I have 80 input ports out of which 70 input ports have width as 32-bits and remaining 10 i/p ports have width as 1-bit and also, I have 80 output ports out of which 70 have width as 32-bit and 10 has width as 1-bit.

Now, I need to configure all these input and output ports to VIO and ILA. But, VIO and ILA allows for configuration upto only 64-bits. 

So, what is the procedure to configure it?

I have tried the following for ILA but couldn't achieve what I wanted.

set_property -dict [list CONFIG.C_NUM_OF_PROBES {1} CONFIG.C_PROBE0_WIDTH {1}] [get_ips ila_0]

Re: How to configure more than 64 probes in VIO and ILA

Hi h20181230210@hyderabad.bits-pilani.ac.in ,


You're command is about right, but you need to specify the number of probes you want. For example, For the VIO:

 set_property -dict [list CONFIG.C_NUM_PROBE_IN {250}] [get_ips vio_0]

Where 250 is the number of Input probes I want for my VIO.

IF you wanted Output probes, just change the "IN" in the above command for "OUT". 

This same command is also valid for the ILA. In the "get_ips" command, change "vio_0" to "ila_0" (or to the correct name of your ILA).

Re: How to configure more than 64 probes in VIO and ILA

Using the command as you said, I can configure the number of i/o probes for vio and ila. But how can be configure the width of the 256 i/o probes provided 100 probes have different width and rest 156 probes have different width?
