Design data often has logical groups of signals, such as all the control signals for a bus protocol, or all the signals used within a state controller. The Verilog language does not have a convenient mechanism for collecting common signals into a group. Instead, designers must use ad-hoc gro...

• Sequence concatenation means b starts one clock after a ends: a ##1 b • You can use an integer variable in place of the delay. E.g., a ##delay b • The following means b completes 2 clock ticks after a completes (regardless of when b starts): a ##2 b.ended ...
随着FPGA和ASIC开发的规模越来越大,功能越来越复杂,对验证和开发的要求越来越高,systemverilog无论在开发还是在验证上都有verilog/vhdl无可比拟的优越性。该文档是systemverilog标准的中文版,具有相当高的参考价值。 上传者:rhett_butler时间:2011-11-19
