 ## Circuit simulation 1. What does the acronym SPICE stand for? a) Simulation Program for Internal Circuit Evaluation b) Simulation Program and Integrated Component Editor c) Standard Program for Integrated Circuit Evaluation d) Simulation Program with Integrated Circuit Emphasis. 2. During a DC circuit analysis: a) all inductors and capacitors are replaced by open-circuits b) all inductors and capacitors are replaced by short-circuits c) inductors are made open-circuit and capacitors made short-circuit d) inductors are made short-circuit and capacitors made open-circuit. 3. A DC circuit analysis is usually performed: a) after a transient analysis b) after a pole-zero analysis c) prior to a transient or pole-zero analysis d) at the same time as performing a transient analysis. 4. The transconductance of a circuit is obtained by: a) dividing the output current by the input voltage b) dividing the input current by the output voltage c) dividing the output voltage by the input current d) dividing the output current by the output voltage. 5. The circuit undergoing SPICE analysis in the example shown below is:  a) a monostable timer b) a two-stage amplifier c) a sinusoidal oscillator d) an astable multivibrator. 6. The transient analysis shown below has been used to produce:  a) a timing diagram b) a pole-zero analysis c) a distortion analysis d) a sensitivity analysis. 7. Hardware description language (HDL) provides a means of accurately modelling the performance of a complex logic arrangement by using: a) accurate truth tables for each device b) Boolean algbra to solve logic functions c) a standard library of pin connecting data d) a formal and rigorous description of the logic. 8. When p and q are both std_ulogic_vector VHDL data types with values 1010 and 0110, respectively the expression "p AND NOT q" evaluates: a) 0001 b) 1100 c) 1011 d) 1000.
