problem about hidding schematic in virtuoso

Dear ppptt,

ppptt said:

I have an analog block in virtuoso (no layout) and I wanna send the design block to others but hope that no detailed inner circuit (schematic) is shown there (only the pins are shown), is it possible?

Did you happen to see Andrew Beckett's response to a similar question a number of years ago at URL:

https://community.cadence.com/cadence_technology_forums/f/custom-ic-design/28952/how-to-protect-your-work-under-cadence

I, personally, am not aware of a way to encrypt a Virtuoso schematic and I believe this is consistent with Andrew's response above. The netlist derived from the schematic of the desired subcircuit can be as Andrew notes. As a result, you could use a file containing the encrypted netlist as an include file. In this case, the schematic calling your encrypted netlist file will include its symbol view to define its IO.

Is that an option you have considered ppptt?
