How to create large networks from a lookup table

RuihW

Hello,

I'm trying to create a network in Virtuoso Schematics. The network has three custom blocks: Block A has 100 instances, Block B has 100k instances, and Block C has 1k instances.

These blocks do NOT have all-to-all connections. Block B only takes a single input from a block A and has a single output to a block C.

The lookup table determines how A's connect to C's through B's. The empty cells mean there is no connection from A to C.

C0 C1 C2 C3 ... C999
A0 B0 B235 ... B7824
A1 B492 B3577 B3578 ...
A2 B1218 B5342 ...
... ... ... ... ... ... ...
A99 B6718 ... B99146

Some examples:

  • A0 connects to C0 through B0 and to C1 through B235.
  • A2 also connects to C0 through B1218.
  • There's no connection between A0 and C2/C3.

My question: what's the most efficient way to create this network?

Should I use SKILL, or build it with Verilog, or something else?

  • Hi,

    I am not an expert in this field but I believe verilog will be more suitable to address your issue.

    Still if you want to do it in SKILL it is feasible but you will face more challenges (you will need to manage instances locations etc.).
    In this case I advise you to use labels instead of wired connections  

    Cheers
