Warning : circuit may not operate . detected 4 non - operational path ( s ) clocked by clock clk with clock skew larger than data delay . see compilation report for details 这个问题好象比较严重，帮我看看，你遇到过没有，他说不能正常工作了？
2.
The contention time lengthened real - time p - persistent simulation results show not only real - time traffic delay performance being enhanced greatly but also common data delay and throughputs not being affected evidently 对竞争延长实时p -持续csma / cd的仿真结果显示不仅它的实时通信量的延时性能大大提高，而且普通数据延时和吞吐量并没有受到显著的影响。
