hi, i am working as a pcb designer, we do multylayer board for semicon industry. we are using protel DXP to do the design. we always follow coustomer schematic which is in PDF format, sometime we dont have certain component, we create the component and its footprint. so, i know a little spice, but i need help to get full spicecode for the component so that we can run simulation first before fabricating the PCB. so could somebody out there help me..
