Title: array of nodes
Post by aaron_do on Jan 13^th, 2014, 11:08pm

Hi all,

I want to create a circuit model with a large number of ports (say 1000). In the Verilog-A manual, it says I can create Vectored Nodes, but I can't get this feature to work. The error I get is:

line 7: Encountered a vector node with a scalar member in a port list, which the software does not support

so are vectored nodes supported or not?

thanks,
Aaron

Can you please show what you've actually tried? Also which simulator you're using?

Regards,

Andrew.

OK sorry, but it seems it was a false alarm.

this is what I originally tried

Quote:

module whatever(out[0], out[3]);
output [3:0] out;
electrical [3:0] out;
...
.......

which I got from this document called "SIMetrix Verilog-A Manual" pg 31. I also tried

module whatever(out[3:0]);

but I got a similar error message. Anyway after you asked for my code I assumed that it is possible to declare a large number of ports, and I found the correct method in the Verilog-A Language Reference Manual Version 1.0., pg 114. I thought I tried this yesterday too but I guess I didn't...
