一般常见错误的 layout 是将clock的 Inverter 放置在电路中间 造成由a 改成 a_ 时其它MOS会接不到换线的讯号，或是改用polygate来接线，将会影响clock的讯号速度 所以最好floor plan时可以将ck_inverter放置在最外侧，换线时直接改ck_inverter的方向或layout就好了，也没有放置中间时和其它和临近的DRC Rule ...

I have downloaded the layout file of the inverter board Devkit-MotorGD from this link https://www.nxp.com/webapp/Download?colCode=LAY-29379_B but it can't be opened by EasyEDA. It may be due to that it had been saved in an EAGLE version below v6? If so, please send me this fil...

I am using Virtuoso 6.1.6-64b. I have created "Graphical Parameterized Cell" for NMOS/PMOS. May I use the same method for CMOS inverter and AND/NAND gates? I would like to parameterize whole layout of AND/NAND gate (interconnect/contacts/PR all can be parameterized). ...
This tutorial will take you step-by-step through the process of handcrafting a simple inverter and perform the design rule checking (DRC) to verify the correctness of the physical design. This layout will correspond to the schematic, which has been created in lab2. Learning the command in Vi...
