    SIMCOM A7672S Power LED Blinking

    Since, some PCBs are creating problems, and some are working, I am sure there is no problem with your design. If the problem were with your design, all PCBs would have failed. I think it's a case of manufacturing error. Some PCBs may have broken traces or short circuits. It often happens. Test...

    Pcb test desing

    Sounds like you are looking for a common test bench for PCB testing. Having a PCB tester is good for doing short-circuit tests and broken trace detection. Well, actually you can make one by yourself. You can make a miniature PCB tester like this one...

    SDC file

    SDC (Synopsys Design Constraints) is a format used to specify the design constraints for digital circuits during the electronic design automation (EDA) process. It is primarily used in the synthesis and timing analysis of digital designs. These constraints guide the EDA tools to optimize the...

    The import of diode models provided by manufacturers in ADS

    Here is a thead about creating new components on ADS. This may help. https://www.edaboard.com/threads/creating-a-new-component-on-ads.373067/ However, creating new component is easier in proteus. There are many tutorials available. You can switch if you wish...

    LED relay opto-coupler MCU connection

    Check the voltage levels at the input of the opto-coupler when the relay is turned on and off. If you're only seeing a high signal regardless of the relay state, there may be an issue with the input signal to the opto-coupler.

    PushPull SMPS with no primary snubber

    Relying solely on the avalanche breakdown of the primary FETs to handle the leakage spike in a push-pull SMPS without a primary snubber is not a recommended practice.

    Open/Short calibration with a LCR meter test probe?

    The difference in open/short calibration procedures between the HM8118 User Manual and the video can be due to various factors, such as differences in instrument models, firmware versions, or calibration standards used by the manufacturer.

    mikroC pro file p18f4431 header

    Double-check the file paths in your project settings. They should point to the correct location where the header files are stored.

    problem in metal fill with ICV

    Since you mentioned that ICV is adding metal fillers according to the log file, but you're not seeing any changes in the design, there might be an issue with how ICV is interacting with ICC2. Check for any error messages or warnings in the ICV log file that might indicate why the changes aren't...
