For a divide by 60 counter using CD4017BE Decade Counter ICs and based on the provided information, here are a few observations and potential issues:

Clock Source Connection:
- The schematic includes a CLOCK_IN net that is connected to J1:Pin_2. However, it's unclear how this clock source is actually configured or where its signal is coming from. Ensure that your clock source provides appropriate logic levels and frequency for the CD4017BE ICs.
Decade Counter Configuration:
- You are using two CD4017BE decade counters (U1 and U2). To achieve a divide-by-60 functionality, the counters must be connected in a cascaded configuration. However, details on how these ICs are interconnected are not provided. Normally, you would connect U1:12 / CARRY OUT to U2:14 / CLOCK for sequential counting.
Reset Configuration:
- CLOCK_RESET net is mentioned, connected to J1:Pin_3, indicating a reset functionality. For a proper reset mechanism, this net should be properly connected to U1:15 / RST and U2:15 / RST.
Output Configuration:
- There are mentions of CLOCK_60_OUT, but without clear details on how the output is generated from the counters. For a divide-by-60 counter, you typically would take the output from the second counter (U2), implying you want the cycle to complete every 60 input clock pulses. You'll likely need to define how you encode a "60 count" across the two counters.
Power Supply Connection:
- Power nets are mentioned, but there's no clear indication of their connections to the ICs. Both U1 and U2 should be connected to a power supply (VDD) and ground (VSS). Typically, this involves U1:16 / VDD and U2:16 / VDD to your positive supply, and U1:8 / VSS and U2:8 / VSS to ground.
No Pull-down/Pull-up Resistors:
- The design does not mention any pull-up or pull-down resistors which might be critical, especially for reset lines or other signals that shouldn't float to avoid undefined states.

Based on these observations and the inherent limitations of textual descriptions:

Recommendation 1: Verify the clock source, ensuring it meets the CD4017BE IC's requirements for voltage levels and frequency.
Recommendation 2: Clarify and correct the connections for cascading the counters, reset functionality, power supply distribution, and the construction of the 60th count output.
Recommendation 3: Consider implementing pull-up/pull-down resistors where needed to ensure defined logic levels on startup or in idle states.

Please check these aspects and adjust your schematic accordingly. If some connections or configurations were intended but not mentioned, kindly provide additional details for more specific advice.

@copilot list all U1 pins in a table format. For each pin provide its pin number, pin name and function.

Below is a table listing the pins of U1, along with their numbers, names, and functions based on the CD4017BE IC:

Table

Pin Number	Pin Name	Function
1	Q5	Output 5
2	Q1	Output 1
3	Q0	Output 0
4	Q2	Output 2
5	Q6	Output 6
6	Q7	Output 7
7	Q3	Output 3
8	VSS	Ground
9	Q8	Output 8
10	Q4	Output 4
11	Q9	Output 9
12	CARRY OUT	Carry Out - Goes high after the last output goes high; used to cascade CD4017B ICs
13	CLOCK INHIBIT	Inhibits clock when high
14	CLOCK	Clock input (Advances the count on the rising edge)
15	RST	Reset - Resets the counter to zero when low
16	VDD	Positive Supply Voltage

This information is derived from the functional description of the CD4017BE IC, where each pin's primary role is defined within the logic of a decade counter/divider, which the CD4017BE is.
