astap การใช้

• Unlike SPICE, which used Modified nodal analysis ( MNA ) to form the system of circuit equations, ASTAP instead used " sparse tableau formulation " ( STA ) to construct and solve a sparse matrix.
• Another point of view is that analysis that keeps track of actual voltages and currents as they change in the presence of AC input signals is too difficult to do with pencil and paper, so simulation programs such as SPICE or ASTAP must be used.
