大家好,小弟求助关于数/模混合版图验证的问题,想问一下,在virtuoso中,做DRC,LVS以及后仿真时,应该怎没做,尤其LVS和后仿真,是不是要将verilog网表和模拟版图转换成某个格式的文件呢?希望各位高人给予指点。谢谢了。
你这问的太笼统了!你们公司用dracula、 还是calibre验证!
对不起,小弟忘了说了,谢谢qu1234guo提醒,我用的是calibre,谢谢各位帮忙啊。
calibre lvs/drc will export gds file from virtuoso before the actual check.
while for post-simulation, first, u need to use rc-extraction tool(startRC/QRC/calibreRC) to extract the rc information from virtuoso, the output will be a sdf/spice netlist file. second, the simulation tool (ADMS/nanosim etc.) will take the verilog netlist as well as sdf/spice netlist as input for the simulation.
