Users can also use Verisium Debug to “pre-randomize” the selected variable to understand the distribution of the randomized values. This feature helps users validate the quality of the constraints and make sure if the values are generated properly. Fig 4. Random variable value distributio...

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
If, however, soft constraints were employed, additional constraints could override the default values, by adding new constraints like the following: constraint test_constraint { gen_valid_crc == 0; } or // In procedural code packet.randomize() with packet_length == 1680; Layered constraints: ...
packet.randomize() with packet_length == 1680; Layered constraints: In my experience, verification environments are most robust when they are built in a layered fashion. A. Component layer Absolute constraints of the class/object being constrained. ...
