Mentor Graphics/Wilson Research Group Functional Verification Study

Smaller designs face greater risk of respins

Research study suggests the maturity of your verification flow determines the likelihood of first-pass success far more than the complexity inherent in design size.

An introduction to System Verilog assertions

Assertions and assertion-based verification (ABV) are hot topics, but many engineering teams remain unfamiliar with the benefits they bring to the design and verification process. This article discusses the rationale behind them, the value they bring across the design and verification process, and offers a step-by-step approach to implementing them.

Symbolic simulation speeds timing closure

Timing closure is a key challenge for today’s complex system-on-chip designs. Static timing analysis (STA) tools automatically analyze signal paths in a design and identify timing-critical paths that limit the clock frequency that can be achieved. Paths that can never be functionally activated or that require multiple cycles for correct operation can be identified as [...]

A holistic approach to low-power verification

The article describes a dedicated low-power functional verification methodology, originally developed at STMicroelectronics (now ST-Ericsson). The article details the content, sequence and effectiveness of the methodology as it was tested on a 45nm system-on-chip design. In order of use, the main components are: A high-level verification language testbench Formal verification Rule checking C function library […]

Multiple cross clock domain verification

Today’s system-on-chip designs often need to encompass multiple asynchronous clocks. This raises the problem of verification for the resultant clock domain crossings. It is becoming apparent that functional simulation alone is not up to the task. Instead, engineers need to consider hybrid methodologies, combining structural and functional verification approaches. The use of assertions is also […]

How VHDL designers can exploit SystemVerilog

SystemVerilog, the standard that originated from Accellera and is now IEEE1800, is not just for Verilog users. VHDL users can also improve their design processes using its proven verification features. Anyone involved in systemon- chip (SoC) design may face a mixed-language environment and will appreciate being able to leverage SystemVerilog with the VHDL portions of […]
