Autodesk Eagle DRC Problems

• Via in Pad Detection


• Is there a EDA tool that actually detects this?
  
  
  • Diptrace
  
  
  • Eagle
  
  
  • Altium
  
  
  
  


• FAB3000
  
  
  • MacroFab's Internal tool set does not
  
  
  
  


• What do we do about this as Engineers?
  
  
  • Write our own tools of course!
  
  
  
  

Datasheet and Schematic Woes

• TI CD4053


• The actual function of the chip was just not in the datasheet


• One typo made the datasheet unusable
  
  
  • Old datasheets strikes again!
  
  
  • This has been fixed sort of
  
  
  
  


• What matters when you read a datasheet?
