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. sequence seq_2; @(posedge clk) a || b; ...

The SystemVerilog syntax defines a sequence in a sequence-endsequence keyword pair with an associated name. The actual chain of events is defined within such a sequence block. A linear sequence is easy to define using SystemVerilog ## operator. The ## operator defines delays in terms of ...
HDL Coder / Model Verification Description The Assertion block checks whether any of the elements of the input signal are 0. If all of the elements are nonzero, the assertion is true (1) and the block does nothing. If not, the block halts the simulation and returns an error message by...
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 only in dynamic simulation, but also in fo
Assertion Based Verification 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...
