WEBENCH® Tools: WEBENCH Issues with negative supply design

Other Parts Discussed in Thread: LM43601, TPS65130

Tool/software: WEBENCH® Design Tools

I have a requirement for a split rail, supply +/- 16V @ 0.1A

I tried various approaches using Webench but all have failed to produce a design. Try this, using Power Architect specify input 4.8-5.2V, output 1 16V 0.1A ripple 2%, output 2 16V 0.1A ripple 2%. When I do this I get a proposed design using a LM2731X for the +ve and an LM43601 for the -ve. Now hit "View Project Details" and "Create Design"  The generated design has errors " Error 16 Unable to create design"

If I retry but with ripple filters, I get a different solution  with an LM2731X and LM25088-1 I have the same problem after :Create Design"

Trying a different tack using +/15V at 0.1A using a TPS65130 gives me a design but if I select PMU_2, "Change Design Inputs"  don't change anything and then hit submit, I get a message "Design Cannot be Created with this Device".

So, I'm stuck unless I go for a flyback approach.  I wanted to avoid that due to the custom transformer.
