User Resources


We are committed to making B2 A/D Spice the best reasonably-priced Spice simulation program possible, and to do that we need your input, so please feel free to email us with your input.

Finally, any non-propriety/non-copyrighted schematics you are willing to share with other B2 A/D Spice users will now be eligible to be posted on our this Resources page.

Please include a brief description of the circuit and let us know if it you prefer that we not include your name or email address with the schematic. (No physical address information other than country will be posted.)

To send circuits to us, just ZIP the CKT files and send them to circuits@beigebag.com
