The UVM factory stands as a central mechanism, empowering users to conjure and dynamically manage UVM components and objects, all without the imperative of explicit instantiation within their code. This registration endeavor affords users the capability to craft instances during simulation, tailoring them to specific parameters and configurations as the need arises.
Factory Registration
In the world of UVM, users wield the power to enlist their personalized components or objects with the UVM factory. This undertaking opens doors to dynamic creation and configuration, significantly alleviating the necessity for coding an object’s constructor and configuration outright. The registered components or objects, now part of the factory’s purview, can be brought to life during simulation, effortlessly bypassing the need for direct, static instantiation. This adaptive approach empowers users with a greater degree of flexibility and configurability within their testbenches.
What is Set Type?
The concept of “set type” serves as a noteworthy mechanism within the factory’s repertoire. It enables users to modify the type of an object slated for creation. This functionality is particularly handy when there’s a desire to override the default type of a specific object, granting the freedom to tailor it according to the unique requirements of the verification environment.
What is Set Instance Override?
“Set instance override” emerges as yet another invaluable tool in the factory’s arsenal. This mechanism extends the capability to tweak specific configuration settings of an object at the moment of its inception. It comes into play when the objective is to adjust certain attributes or properties of an object. For instance, users can alter parameters like address values or data width while preserving the core object type intact. This level of customization proves instrumental in fine-tuning the behavior of objects as they traverse the verification environment.
In summation, factory registration in the UVM landscape is a dynamic process that empowers users to create and configure components and objects with flexibility and agility. “Set type” is your go-to option for altering object types, while “set instance override” steps in when fine-grained customization of specific object attributes is required. Together, these mechanisms offer a spectrum of possibilities to enhance the adaptability and tailor the verification environment to suit your unique needs.
