4、利用向导画封装,提示 Performing DRC... No DRC errors detected. E- (SPMHA1-70): Pin is outside of the extents. E- *Error* axlDBGetPad: argument #1 should be any user-defined (other) type (type template = "ogg") - nil 这是由于参数设置错误,比如SOIC封装的芯片,左右两排的引脚间距...
看session log，具体错在哪里。另外先drc 肿么看啊，点了没反应，Windows--Session Log。是先DRC的，...
查看报告、数据库检查: 查看报告:工具栏toolsreports或quick reports,常用的右未连接引脚unconnected pins report,动态铜皮状态(是否smooth状态)shape dynamic state,没有指定网络的铜皮shape no net,孤岛 shape islands, drc 错误 design rules check reporto数据库检査(在铺铜、drc等各种检查之后进行):toolsdatabase...
The minimum design rule check (DRC) rules fail to capture many potential yield issues, while relaxing DRC rules causes an unacceptable increase in design area. These systematic shape variations are dependent on specific layout-shape context, and result in predictable catastrophic errors such as ...
The Allegro FPGA System Planner has a built-in DRC engine that incorporates the rules provided by FPGA vendors for pin assignment, reference voltages, and terminations. This rules-based engine prevents PCB physical prototype iterations as the FPGAs are always correctly connected. ...
ForSame Net Spacing, users can define clearance for same-net objects. Objects of the same net will not flag a violation without same-net spacing rules since no short is detected. Same-net collisions can be an issue when the DRC doesn’t recognize certain object types (e.g., over...

I have techfile project where I keep techfile.db and file with ext .oa. That files were maked from copying them from converted DRC project. Convertion of DRC project from cds5 to 6 format was with no errors. When I try to load layout from My_ADC project using DRC ...
The resulting layout must verify some geometric rules dependent on the technology(design rules).For enforcing it,a Design Rule Check(DRC) is performed.Optionally, some electrical errors (e.g.shorts) can also be detected using an Electrical Rule Check(ERC).Then, the layout should be compared to...
