Pin placement speed up

Hi,

I have a skill code to create large layout arrays of my instances. So far i created sub arrays and use them to create larger arrays and in this way the procedure becomes very fast. However, i have a pin which is different for every cell in my array so i have to sweep the whole array and place it on every cell. Is there a way to instantiate these pins on the final array in a faster method or in a parallel way so the execution time becomes faster? I thought of a mosaic but i need to maintain connectivity information with the schematic.

For example i have a subarray with pin A<1:10>, i place 10 subarrays so i have A<1:100> on the final array. When it comes to big numbers, X*X placement is time consuming.

You should be able to get the pin name and shape using this database path

If you dont see the nets, you may need to do a Update Components and Nets

Heres some more info on pins

I don't really see why this should be slow - if it's an array, I'd expect the pins to be regularly spaced.

Without seeing the code, it's rather hard to know why it would be slow. You can't place them in parallel (various parts of the system involved are are single-threaded), but this doesn't sound a particularly expensive task so I would expect it to be very fast if the code was written correctly.

It may be easier to deal with this through customer support so that you can share your code and the data you're using so that we can give advice on how best to improve it.

Regards,

Andrew.
