What is an API in UVM?

Abbreviations. API – Application Programming Interface.

What is API in SV?

API-based verification: Effective reuse of verification environment components. api_top is a UVM component having instances of all block level API classes. api_b3.sv is a UVM component containing all required APIs to program B3 design block through host interface driver.

What is interface class in SV?

In SystemVerilog, an interface class declares a number of method prototypes, data types and parameters which together specify how the classes that need those features can interact. In other words, an interface class has neither state nor implementation.

What is a DPI call?

The SystemVerilog Direct Programming Interface (DPI) is basically an interface between SystemVerilog and a foreign programming language, in particular the C language. It allows the designer to easily call C functions from SystemVerilog and to export SystemVerilog functions, so that they can be called from C.

Is UVM is independent of SystemVerilog?

Is UVM independent of SystemVerilog? No. UVM is built on SystemVerilog and hence you cannot run UVM with any tool that does not support SystemVerilog.

What is API in VLSI?

API is the acronym for Application Programming Interface, which is a software intermediary that allows two applications to talk to each other.

Why do we need interfaces in SV?

Interfaces are a major new construct in SystemVerilog, created specifically to encapsulate the communication between blocks, allowing a smooth refinement from abstract system-level through successive steps down to lower RTL and structural levels of the design. Interfaces also facilitate design re-use.

Are there pointers in SystemVerilog?

SystemVerilog objects are referenced using an object handle. There are some differences between a C pointer and a SystemVerilog object handle. C pointers give programmers a lot of latitude in how a pointer can be used. The rules governing the usage of SystemVerilog object handles are much more restrictive.

What is DPI and API?

To be more specific, the analytics tool would specify a data interface, i.e., a schema, for its input, rather than an application programming interface (API). This is what we are calling a Data Programming Interface (DPI).

What is the advantage of UVM over SystemVerilog?

Separating Tests from Testbenches: Tests in terms of stimulus/sequences are kept separate from the actual testbench hierarchy and hence stimulus can be reused across projects. Sequence methodology: It gives good control on stimulus generation.

Is UVM better than System Verilog?

UVM is a SystemVerilog class library explicitly designed to help you build modular reusable verification components and test-benches. Creating each components using factory enables them to be overridden in different tests or environments without changing underlying code base. …
