Webfunctions can not include timing delays, like posedge, negedge, # delay, which means that functions should be executed in "zero" time delay. ... A function begins with keyword function and ends with keyword endfunction; inputs are declared after the keyword function. Example - Simple Function : WebSVA provides a keyword to represent these events called “sequence”. SVA Sequence example. In the below example the sequence seq_1 checks that the signal “a” is high on every positive edge of the clock. If the signal “a” is not high on any positive clock edge, the assertion will fail. sequence seq_1; @(posedge clk) a==1; endsequence
