WebBecause SystemVerilog assertions evaluate in the preponed region, it can only detect value of the given signal in the preponed region. When value of the signal is 1 on the first edge and then 0 on the next edge, a negative edge is assumed to have happened. So, this requires 2 clocks to be identified. WebThose clarifications might change some of the restrictions of programs, clocking blocks, event regions, as well as some of the behavior described in this paper. As updates become available, this paper will be updated to reflect those changes and will be posted to the www.sunburst-design.comweb page.
