Hi Guys,
When putting a schematic together, what is the best process/practices for integrating a new IC into a design? I'm just curious what other peoples approach is to the subject. Lets just say for example an IC is already selected (not an MCU), you don't know much about it, you've got the data sheet and a user guide. What do you do next?
My approach is as follows:
- Create a google doc where I can write notes from reading the data sheet, user guide, test cases and any other info along with way. I embed links to references
as well. - Understand the general function of the IC.
- Understand the functions behind each pin on the IC.
- Determine what the power requirements. Use the reference design as a template. Does it need a buck, LDO, etc?
- Determine how it will this interface with any other ICs in the design. I2C, SPI, etc?
- Determine test points or jumper points that could be useful during testing/bring up.
- Determine test cases with pass/fail parameters for validation.
- Complete the schematic.
Cheers,
