WEEK 11

 

Title: Test board design

    This week the first test board was designed with all the circuitry on testing the result, the output of the IDT. I was routing two clock generator, the first one use the astable multivibrator and the other one use the hex schmitt inverter. It is harder to design as the sensor design keeps on displaying rules violation due to the board rules does not go lesser than 0.3mm clearance. But the IDT gap is 0.1mm. But I don't want the clearance to be 0.1mm as it will cause me problems during soldering. Smaller clearance means that it is most likely your soldering will be shorted to the ground connected polygon due to overflow of the soldering lead.

The test board design is done by setting the software to ignore clearance inside the component itself.
