Understanding Logic Equivalence Check (LEC) Flow and Its …
WEBLogic Equivalence Check, popularly known as LEC is one of the most important parts of the ASIC VLSI design. Formal verification techniques have been developed using mathematical proof rather than simulation or test vectors to provide a higher level of verification confidence on properties. For example, the implementation can be either a Verilog ...
System Verilog Assertions Simplified - Design And Reuse
WEBSystem Verilog Assertions Simplified. By Smit Patel, eInfochips. Abstract. Assertion is a very powerful feature of System Verilog HVL (Hardware Verification Language). Nowadays it is widely adopted and used in most of the design verification projects. This article explains the concurrent assertions syntaxes, simple examples of their usage and ...
Demystifying MIPI C-PHY / DPHY Subsystem - Design And Reuse
WEBFor D-PHY this can be accomplished by using four-lane D-PHY, using 10 wires, each Lane running at 1.0Gbps/lane. To obtain the same aggregate data rate at the same or lower transition rate with C-PHY, we can use two-lanes C-PHY, with 6 wires, running at 0.875Gsps, which is less than the 1.0Gsps for the D-PHY.
System Verilog Macro: A Powerful Feature for Design Verification …
WEBSV macro is one of the most powerful features out there and if used properly with a thorough understanding and applied wisely in a DV project, it can help to save a lot of time and can make the code more readable and efficient. This paper shows how, using SV macro with the proper syntaxes, a DV engineer can break up the larger complex code in smaller chunk and can reuse it at many places.
