I'm working with the CIW version 5.10.41 and came across with the
following problem when doing schematics (Virtuoso schematic composer)
for a full custom mixed signal design:
Let's assume that I have a 3 bit bus going into an instance (I), and I
need 8 of these instances all together. These instances should be hooked
up with binary weighted signals. So the top level would be something
I<0:7> connected with a wire labeled (expanded form):
so that the incoming 3 bit bus is different for each instance and can
not be simply labeled with a<(2:0)*4> or similar compact
expression. I don't have access to standard cell library with this
specific DK, so vhdl code + synthesis is out of question. I can compress
the string above a little bit e.g.
a<2:0>,a<2:1>,b<0>,.... b<2:0>, but it's not
helping very much when extending the concept from 3 bits to 10 bits. Notice, that only the prefix changes, the index is the same 3 bit pattern (2:0) for each instance. I
was wondering if it would be possible to take the instance index as an
input argument and perform a decimal to binary conversion for it and finally
substitute all zeros with prefix a and all ones with prefix b. However, I
don't know how this should be implemented in practice.
embedded verilog module?
Answering to my own question...
I wrote a few lines of matlab code that generates the desired wire labels to separate text files. Then I copy pasted these to appropriate places and got the job done. Maybe not very elegant solution but worked fine for me. It was afraid that Virtuoso does not support that long wire labels but it does - What a relief.
