Proof: Pc 12

Let's prove the following theorem:

if the following are true:
  • instruction #4 is addi dst=4 src=4 imm=1
  • the PC at time 12 = 4

then the PC at time 13 = 5

Given
1 instruction #4 is addi dst=4 src=4 imm=1
2 the PC at time 12 = 4
Proof Table
# Claim Reason
1 the PC at time (12 + 1) = 4 + 1 if instruction #4 is addi dst=4 src=4 imm=1 and the PC at time 12 = 4, then the PC at time (12 + 1) = 4 + 1
2 12 + 1 = 13 12 + 1 = 13
3 4 + 1 = 5 4 + 1 = 5
4 the PC at time (12 + 1) = the PC at time 13 if 12 + 1 = 13, then the PC at time (12 + 1) = the PC at time 13
5 the PC at time 13 = 5 if the PC at time (12 + 1) = 4 + 1 and the PC at time (12 + 1) = the PC at time 13 and 4 + 1 = 5, then the PC at time 13 = 5
