[Spectre netlist] How to contain/have all the subckt definitions of sub-blocks and devices included in a top level cell inside the top level subckt definition ?

Fahmy,

It's not clear what exactly you're doing. However, perhaps using the MTS (multi-technology support) mode in ADE would help you - this will create scoped netlists. I've not tried (and don't have time right now) to test how you might do this from an OCEAN script (I'd start by doing it in ADE and then saving an OCEAN script).

Thanks for the prompt response, I think my initial explanation was indeed not very clear (I will try to rephrase below)

The MTS/scoped netlists sounds like a potential solution, is there a way to create a scoped netlist for all instances, i.e all of the subckts definitions are placed inside the top level subckt, alternatively, I can achieve the same by post processing the netlist and make sure that all of the subckt definitions are moved inside that of the top level, any expected drawbacks ?

back to the issue itself, the netlister in the PDK I am using is assigning random/varying names to the pcells' subckt definitions of the primitive devices during netlisting, so as an example if I have 3 nmos transistors in the design [I0, I1, I2] they will get assigned to subckts called "transistor_subckt_15", "transistor_subckt_16", "transistor_subckt_22" , if the design is re-netlisted those subckts names will change, which is not an issue as the instances will point to the new subckt names correctly, but things started going wrong in my case because I am including an additional netlist which in some cases ended up containing one or more of the names are already used and point to a completely different device, the subckt "transistor_pcell_15" could be pointing to a a low leakage nmos in the first netlist, and a high speed pmos in the second netlist !

Thanks, 

Fahmy
