  1. PS1 and PS2 Solutions • Solutions for PS1 • Solution for PS2 EE694v-Verification-Lect11

  2. PS1 Solution • The ENTITY for any soluiton • --============================================================================= • -- Generic Function Unit Entity • ------------------------------------------------------------------------------- • ENTITY generic_function IS • PORT (A,B,G3,G2,G1,G0 : IN BIT; • R : OUT BIT); • END generic_function; • This entity has all inputs at type BIT EE694v-Verification-Lect11

  3. PS1 ARCHITECTURE 1 • A simple Boolean Equation • ARCHITECTURE one OF generic_function IS • BEGIN • R <= (NOT A AND NOT B AND G0) OR • (NOT A AND B AND G1) OR • ( A AND NOT B AND G2) OR • ( A AND B AND G3); • END one; EE694v-Verification-Lect11

  4. PS1 ARCHITECTURE 2 • Conditional signal assignment statement solution • ARCHITECTURE two OF generic_function IS • BEGIN • R <= G0 after 15 ns WHEN A = '0' AND B = '0' ELSE • G1 after 15 ns WHEN A = '0' AND B = '1' ELSE • G2 after 15 ns WHEN A = '1' AND B = '0' ELSE • G3 after 15 ns ; • END two; EE694v-Verification-Lect11

  5. PS1 ARCHITECTURE 3 • Selected signal assignment statement solution • ARCHITECTURE three OF generic_function IS • BEGIN • WITH A&B SELECT • R <= G0 WHEN “00”, • G1 WHEN “01”, • G2 WHEN “10”, • G3 WHEN “11”; • END one; EE694v-Verification-Lect11

  6. Simulation Results • Simulation results look like: EE694v-Verification-Lect11

  7. PS2 Solution • The carry chain EE694v-Verification-Lect11

  8. The slice • Declarative region EE694v-Verification-Lect11

  9. The slice • The statements • Instantiation EE694v-Verification-Lect11

  10. Simulation Results • PS2 results EE694v-Verification-Lect11
