Proof: Pc 3

Let's prove the following theorem:

if the following are true:
  • instruction #3 is addi dst=5 src=0 imm=4
  • the PC at time 3 = 3

then the PC at time 4 = 4

Given
1 instruction #3 is addi dst=5 src=0 imm=4
2 the PC at time 3 = 3
Proof Table
# Claim Reason
1 the PC at time (3 + 1) = 3 + 1 if instruction #3 is addi dst=5 src=0 imm=4 and the PC at time 3 = 3, then the PC at time (3 + 1) = 3 + 1
2 3 + 1 = 4 3 + 1 = 4
3 the PC at time (3 + 1) = the PC at time 4 if 3 + 1 = 4, then the PC at time (3 + 1) = the PC at time 4
4 the PC at time 4 = 4 if the PC at time (3 + 1) = 3 + 1 and the PC at time (3 + 1) = the PC at time 4 and 3 + 1 = 4, then the PC at time 4 = 4
