  3. Continuity Test
    • Use a continuity tester or multimeter to ensure all ground points are connected properly.
  4. Initial Power On
    • Power the circuit, ensuring the battery is connected.
    • Measure the voltage at U1:VCC, confirming it receives 3V.
  5. Switches Test
    • Press each switch (SW1, SW2, SW3, SW4, SW5)\text{(SW1, SW2, SW3, SW4, SW5)}.
    • Ensure corresponding resistors and nets reflect the expected behavior.
  6. Logic IC Functionality Check

  9. Overall Functionality Test
    • Power the entire circuit and observe it in operation.
    • Use oscilloscope and multimeter for detailed signal tracing and verification.
  10. Debugging
  • If a test step fails, use schematics and datasheets to trace potential issues.
  • Rework any failed solder joints or replace faulty components as necessary.
By following these steps, you'll be able to validate the functionality of your project comprehensively. Let me know if any additional details or steps are needed!

@copilot Check that all reset/enable have an external pull-up or pull-down resistors. Report action items in an ordered list.
1y
In your project, the SN74LS76AN comprises various reset (SD, CD) and enable pins which may require external pull-up or pull-down resistors to ensure proper operation, avoiding floating states. Based on the given connections, let’s verify the requirements for each applicable pin and determine necessary actions.
Reset/Enable Pins and Their Connections in Your Project:
  • U1 (SN74LS76AN)
    • Pin 2 (SD): Connected to Net 7.
      • Net 7 Members:
        • SW4:$P2$
        • R5:$P1$
        • U1:$SD$
    • Pin 3 (CD): Connected to Net 8.
      • Net 8 Members:
        • SW5:$P2$
        • U1:$CD$
        • R6:$P1$
Based on this information, let's check the presence of pull-up or pull-down resistors.
Actions to Ensure Correct Behavior:
  1. Pin 2 (SD):
    • Current Condition: SD is connected to Net 7, which includes SW4, R5, and U1. R5 acts as a pull-down resistor with a value of 220 Ω.
    • Action Item: No further action required for SD as it already has a pull-down resistor.
  2. Pin 3 (CD):
    • Current Condition: CD is connected to Net 8, which includes SW5, R6, and U1. R6 acts as a pull-down resistor with a value of 220 Ω.
    • Action Item: No further action required for CD as it already has a pull-down resistor.
Summary Action Items:
  • Double-check for correct installation of R5 (220 Ω pull-down) connected to SD (pin 2).
  • Double-check for correct installation of R6 (220 Ω pull-down) connected to CD (pin 3).
You may proceed by verifying and ensuring the resistors (R5 and R6) are correctly installed on your PCB layout in Flux. Ensure that the connections are secure, and there are no unintended open circuits or floating states for SD and CD pins.
