1. Power Connections:
   • Connect $IC1:VCC$ to the 5V supply ($Net 6$).
   • Connect $IC1:3V3OUT$ to $J4:1$ and $J4:3$, providing 3.3V output.
   • Ensure the $IC1:GND$ pins and capacitor grounds such as $C1:P2$ are connected to the ground ($Net 5$).
2. USB Data Lines:
   • $IC1:USBD+$ should connect to $J1:D+$ via $Net 2$.
   • $IC1:USBD-$ should connect to $J1:D-$ via $Net 4$.
3. UART Interfaces:
   • TXD (Transmit Data) from FT232RL: Connect $IC1:TXD$ to $J2:Pin_3$ via $Net 27$.
   • RXD (Receive Data) for FT232RL: Connect $IC1:RXD$ to $J2:Pin_2$ via $Net 25$.
4. Capacitors:
   • Place decoupling capacitors close to power pins. For $C1$, ensure it decouples right near power inputs.
   • $C4:10uF$ capacitor should filter on the 5V rail ($Net 6$), ensuring stable VCC.
5. Control Signals:
   • Ensure connections for DTR, CTS, RTS, etc., are correctly mapped:
     • DTR: $IC1:DTR$ connected to $DTR$ via $Net 20$.
     • CTS: $IC1:CTS$ connected to $CTS$ via $Net 28$.

1. Additional Decoupling Capacitors:
   • It is good practice to add a 0.1µF capacitor close to VCCIO ($IC1:VCCIO$) for decoupling.
2. LED Status Indicators:
   • Ensure that you have resistors for current limiting in series with your LEDs ($LED1$, $LED2$, and $LED3$). For example, connect the anode of the LED to VCC (with a current-limiting resistor like 1kΩ in series) and the cathode to a control signal.
3. Reset Circuit:
   • You may want to connect a pull-up resistor (e.g., 10kΩ) to the $IC1:RESET#$ pin to prevent unintended resets.
4. Check USB Communication Lines:
   • Ensure proper routing and differential signal integrity for D+ and D- lines, including matching trace lengths and using appropriate impedance control per USB specifications.

• Connect J1:VBUS (Pins 3, 4, 13, 14) together to form a single voltage source.

• Connect J1:VBUS $3$ to J1:VBUS $4$, J1:VBUS $13$, and J1:VBUS $14$.

• Connect J1:GND $1$ to J1:GND $2$, J1:GND $15$, and J1:GND $16$.

• Connect $IC1:10$ to $J6:Pin_1$.

1. Power Nets:
   • VCC, VDD, VEE, VSS: Follow commonly accepted power net names.
   • Voltage Level: Include voltage levels in net names (e.g., VCC_3V3 for 3.3V, VCC_5V for 5V).
2. Ground Nets:
   • GND: The standard naming for ground nets.
   • Specific Grounds: If you have separate grounds (analog, digital), name them AGND, DGND respectively.
3. Signals:
   • Descriptive Names: Use names that describe the function of the signal (e.g., TXD for transmit data, RXD for receive data).
   • Hierarchy/Grouping: Prefix with hierarchical or functional blocks (e.g., USB_D+ for USB data positive, FPGA_CLK for FPGA clock).
   • Bus Signals: Use names that indicate they are part of a bus (e.g., DATA[7:0]).
4. Control Signals:
   • Active Low: Usually indicated by a trailing underscore (e.g., RESET_, ENABLE_).
5. Test Signals:
   • Test Points: Mark them as TP1, TP2, etc.
   • Specific Test Names: If for specific functions, name accordingly (e.g., TEST_CLK).

• You could name the net something meaningful based on the function, such as DCD_CTRL if the net connects to a Data Carrier Detect control line, or simply SIG_CONN.

1. Draw a net between IC1:10 and J6:Pin_1.
2. Label the net with DCD_CONN.
