How to assign two dimensional bus notation in schematics

Dear delgsy,

This need just rises and I found out that it has been asked here.

I have, let's say, 100 10-bit counters and would like to plot counter value as y-axis and counter ID as x-axis.

Unless I am overlooking something in the post you refer to, the request in the Forum post was for a means to express in a format Virtuoso can understand multiple instances of a multi-bit bus (as an example). Your question, in my mind, is different.

With respect to the subject of the post you refer to, in case you happened to search the On-line support site and did not see it, an alternative methodology is proposed (due to limitations of SKILL) at URL:

Your request relates to plotting counter value versus counter instance - which seems totally different. Am I misunderstanding your request? I think you will need to post-process your results to create a text file of counter instance vs counter value (can be done in Assembler) and then import them into ViVA using the Calculator (or an ocean script) to plot them. To my knowledge, the counter instance does not natively produce any kind of list or waveform and hence can not be natively plotted in ViVA.

Hello Shawn,

No, you do not misunderstand anything.
Actually, there are two different thing, one is the 2D bus notation, let's say [G, H] and the other one is how to plot value of H vs G.
I was thinking, by having a possibility to do 2D bus notation, it is half way to achieve that plot.
The other benefit is I do not need to draw explicitly each channel in the schematic to easily have a separate output per channel, unless there is a way already to do this that I do not know.

maybe the picture below can make this clearer.
