Hello I used the circuit generator at Texas Instruments WEBBENCH designer for the LM3481 boost converter.. I copied the schematic exactly.. First is a copy of their schematic.. Second is a copy of mine in Multisim.

When I run it it says "Unable to converge during transient analysis. Consider increasing ABSTOL, VNTOL, and RELTOL options".. I have tried to increase these and it seems to run for a few mins then quits again. I really would like to test this boost converter.
