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; ...
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

例如,下面的断言将在图1.8中几乎每个周期(除了周期1和5)上创建新的线程。 notreq:assertproperty(!req[0]|->##10!gnt[0]); 参考文献: 1.《Formal Verification——An Essential Toolkit For Modern VLSI Design》
SystemVerilog has integrated a set of constructs that helps you to build assertions and closely couple them with the rest of your design or verification code. One of the main features of SystemVerilog assertion constructs is that they are part of the language itself. This means you can use ...
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...
