Nowadays, Incorporating the Assertions in the Verification of the design is common to verify RTL behavior against the design specification. Independent of the Hardware Verification Language( HVL ) viz. Verilog, SystemVerilog, UVM used for performing verification of the RTL, the addition of the assertions inside the Verification code helps to quickly trace bugs. The primary advantage of using SV assertion over Verilog-based behavior check is a simplistic implementation of the complex sequence that can consume a good amount of time and effort in Verilog-based codes. SystemVerilog assertion has a limited set of operators so learning them is not difficult but choosing a specific operator to meet design specifications comes with years of experience. In this course, We will go through series of examples to build a foundation on choosing a correct assertion strategy to verify the RTL Behavior. The assertion comes in three flavors viz. Immediate Assertion, Deferred Immediate assertion, Final deferred immediate assertion, and Concurrent Assertion. An assertion is a code responsible for verifying the behavior of the design. Full Verification of the design essentially includes verification in Temporal as well as non-temporal domains. SV Immediate and Deferred assertions allow us to verify the functionality of the design in the Non-Temporal region and Concurrent assertion allows us to verify the design in the Temporal region.
