We are using a CYBLE-022001-00 module and I need 2 ADC SAR on the design. However, when I perform a build the error indicates 2 clocks are required and 1 is available.

Any way around this?

Use a component-external clock connected to Both ADCs

OK. However this as an existing hardware design with no external clocks for SAR ADCs.

Sorry, what are you targeting with "However"? I am not talking about a chip external clock. Set the ADC property "External clock" and drop a clock component onto your topdesign and configure the frequency. Connect the clock to both ADCs.

The CYBLE-022001-00 module has only 1 12-bit SAR ADC. Hence, you cannot use 2 SAR ADCs in your project. You could rather use different channels on the same ADC for your conversion.
