MEP EP#317: When an Alien Craps

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?
