Subject: [TN] impedance value very high

I have a puzzling question for you impedance experts:

A customer is asking for a PCB characteristic impedance for a single
trace to be 332 Ohms +/- 5%.

I've never seen a requirement for an impedance to be this high.  Has
anyone here seen this before?  HyperLynx is choking on this.

Thank you in advance for your input, it is greatly appreciated.
