Calculator error on arithmetic operation on the reading of digital bus

The numConv function will return the number as a string. So you could convert it to an actual integer using:

atoi(numConv(value(VT("/COUNTER4V_A<31:0>") 1u ) "dec" t))

and then you could divide that by 9997.

Dear delgsy,

I have a digital bus as an output of verilog block.
Then putting these expressions on calculator gives me error.
value(VT("/COUNTER4V_A<31:0>") 1u ) / 9997

I have an alternative that may satisfy your end needs - which I am assuming is to include an ADE output with the value of your digital bus at one or more times. It can easily be modified to allow you to perform mathematical expressions on the bus value using the atoi() function. The same basic methology may be used to add the bus as a digital waveform to a ViVA plot that can be plotted from ADE following a simulation if you still need or want to plot it as well as procure its value(s) at some time(s).

I put together a test bench to create an analog waveform bus to both convert to a digital waveform as well as procure its value as a digital bus and have attached my effort. I hope it provides enough detail for it to be understandable!

I hope this helps delgsy!

(PS - i did not see Andrew's response!...Oops! I am sure that will be helpful delgsy.
