EMI EMC Testing
Here is the question that I get asked a lot.
Can you do the test for EMI and EMC on the software itself prior so that we don't have to do physcial testing as much and pass all the standards so that the product launch happens faster??
To everyone in the community, what are your thoughts?
Can we atleast do RE/RS testing on Kicad or altium or any other software?
This is for any wireless product design.

Ansys and other Simulation software's are there to check Signal integrity, Power Integrity, EMI analysis on the digital design.
for complex design, it is a good practice to do the analysis, improve the design based on points from analysis and then go for manufacturing.
Many company provides such service
Field Theory is one company I know in US who does that for RF, antenna's
So without even having testing equipments we can analyse the design and then for good practises maybe use rf tools?
No, we cannot test it prior to the entire assembly being finished. Why? The EMC is not a character of the PCB, but the character of the entire system. Wires, connectors, enclosures, everything.
True. Just to minimise the time required to test maybe first
As @Petr Dvořák told testing can only happen after you get pcb or product in hand, before that you can only do design level analysis, which is also critical for complex designs
You can go though some resources online
Yes thanks..
For embedded products, its usually the firmware that's the longest development path. Most compliance testing can be done without the production FW. One approach I've used is that once we have the hardware built and BSP FW done, have an seperate developer write the EMC test FW in parallel to the team writing the application FW. For wireless products, or sleepy products, you usually require special EMC FW to excercise the product during testing anyway. This way, EMC testing can be either complete, or at least completely de-risked in parallel to the application FW development process.
