Project Overview and Analysis
Thought for 22 sec
You can connect the sublayout to the MCC board by feeding the 3.3V supply from the MCC into your sublayout's 3V3 power net. This means:
-
Power Connection:
- Use (or add) a terminal or net portal labeled 3V3 on your sublayout that is connected to the 3.3V rail.
- Wire the MCC board’s 3.3V output to this terminal so that the module and its supporting circuitry receive power from the external 3.3V supply.
-
Common Ground:
- Ensure that the ground (GND) from the MCC board is also tied to your sublayout's ground (using the proper c2e41937-4268-256c-7ae9-cb8cfb60aed3 component) so that both circuits share the same reference.
This approach lets you power the sublayout solely from the MCC board while maintaining the required connections for proper operation.
Would you like me to suggest schematic changes to add or adjust the net portal/terminal connecting the 3.3V supply?
can I run this layout without connecting the 5v terminal
Thought for 20 sec
Yes, you can run the layout without connecting the 5V terminal if your design only requires the 3.3V supply. Here are a few points to consider:
-
Unused Terminal:
If no components in your sublayout are actively using the 5V rail, leaving the 5V terminal unconnected is acceptable. However, make sure that none of the parts require a 5V input for proper operation. -
DRC Considerations:
Leaving an expected net unconnected might trigger design rule check warnings. You can either ignore these if they're non-critical or update the schematic to mark the 5V terminal as unused or "No Connect" so that DRC rules do not flag it. -
Power Integrity:
Ensure that any parts previously intended to be powered by 5V either operate correctly at 3.3V (if that’s within their acceptable range) or have alternate power configurations (e.g., via internal regulators).
Would you like to update the schematic to mark the 5V terminal as not used or to suppress its connection in DRC?
