Warning 097: Unable to determine the value of pull resistor {resistor} on {tap} [on chain '{chain}']

Unable to determine the value of pull resistor resistor on tap [on chain 'chain']. Check it is between the recommended values of minvalue and maxvalue.

TDI or TDO net is pulled to power by a resistor but its value is not specified or cannot be determined from the BOM data. If the project contains multiple chains then the name of the chain in question is reported, otherwise that portion of the message is omitted.
