What is the LPE QA flow in UMC?
12. What kind of action will be taken in UMC if there are noticeable differences between silicon data and RC extraction result? We will try to find out the possible causes of differences: the measurement error, process file typo, RC extraction tool accuracy issues or if the process documents is out of date. Once the cause is determined, we will feedback the data to the corresponding department and solve the problem. Back to Top LVS Questions 1. What should a customer do if a resistor in the layout is not recognized by UMC’s LVS command file? Some resistors that are customer made cannot be recognized in our official LVS command files. In these cases, DS can provide help to create a customized command file by customers’ request. Back to Top 2. How to compile a net_list with parameters on the sub_circuit line by Dracula? Simply add command “.PARAM” before the circuit description block in the SPICE/CDL net_list file will have Dracula take the parameters on the sub_circuit. Back to Top 3. W
