SystemVerilog assertion sequence A sequence with a logical relationship Below sequence, seq_2 checks that on every positive edge of the clock, either signal “a” or signal “b” is high. If both the signals are low, the assertion will fail. ...
基于断言的验证(ABV)是一种将断言用作验证数字设计正确性的主要手段的技术。断言是描述在设计中必须始终为真的条件的语句,通常使用硬件描述语言(如 SystemVerilog 或 VHDL)编写。 ABV 背后的基本思想是结合使用功能和形式验证设计是否满足其功能要求。SystemVerilog 断言用于定义设计的预期行为,形式验证技术用于检查设计在...
Title:Using OVL for Assertion-Based Verification of Verilog and VHDL Designs Description:Open Verification Library (OVL) is a library of property checkers for digital circuit descriptions written in popular Hardware Description Languages and maintained by Accelera. The OVL checkers could be used not onl...
An assertion is a statement that a given property is required to be true, and a directive to verification tools to verify that the property does hold。 1.2断言的好处 获取设计者的目的; 允许协议被定义和验证; 减少投入到市场的时间; 很大程度上简化可重用IP核的验证; ...

During formal verification, the condition may be interpreted as a condition to be proven by the verifier. For example, if we write assert initial_value <= max_value; and initial_value is larger than max_value when the statement is executed during simulation, the simulator will let us know....
But ABV has rarely been applied to analog/mixed-signal verification. This article looks at challenges in analog/mixed-signal verification, evaluates how the ABV concept can address some of those challenges, and shows how languages such as Property Specification Language (PSL) and SystemVerilog ...
