The present disclosure relates to a system and method for fluid parameterized cell (Pcell) evaluation. Embodiments may include displaying a fluid Pcell in a first format. Embodiments may further include identifying a first state in a fluid Pcell evaluation code. In some embodiments, the first state may indicate that alterations are being made to the fluid Pcell. Embodiments may also include displaying instances of the fluid Pcell in a second format based upon, at least in part, identifying the first state in the fluid Pcell evaluation code. Embodiments may further include identifying a second state in the fluid Pcell evaluation code. In some embodiments, the second state may indicate the completion of the alterations to the fluid Pcell. Embodiments may also include displaying a final instance of the fluid Pcell in the first format based upon, at least in part, identifying the second state in the fluid Pcell evaluation code.

System and method for fluid parameterized cell evaluation

A version management system for fluid guard ring (FGR) PCells uses one or more new version management parameters that are added to the FGR PCell definition to manage the source code versions for a PCell. The system saves instance layout information with a version management parameter that identifies the current PCell source code version for each FGR PCell instance. When evaluated using a newer version of the PCell source code, the instance layout information generated with a previous version of PCell source code can be retrieved. The retrieved layout information will be used during evaluation of the PCell to ensure the integrity of the PCell geometries that were previously verified. The saved layout information will be uniquely identifiable with a hash code of the name-value pairs for one or more parameters associated with the PCell instance.
