Proof: Addi Insn 1

Let's prove the following theorem:

if the following are true:
  • instruction #1 is addi dst=8 src=4 imm=0
  • the PC at time 1 = 1
  • value of cell 4 at time 1 = 11

then value of cell 8 at time 2 = 11

Given
1 instruction #1 is addi dst=8 src=4 imm=0
2 the PC at time 1 = 1
3 value of cell 4 at time 1 = 11
Proof Table
# Claim Reason
1 value of cell 8 at time (1 + 1) = (value of cell 4 at time 1) + 0 if instruction #1 is addi dst=8 src=4 imm=0 and the PC at time 1 = 1, then value of cell 8 at time (1 + 1) = (value of cell 4 at time 1) + 0
2 1 + 1 = 2 1 + 1 = 2
3 value of cell 8 at time (1 + 1) = value of cell 8 at time 2 if 1 + 1 = 2, then value of cell 8 at time (1 + 1) = value of cell 8 at time 2
4 value of cell 8 at time 2 = (value of cell 4 at time 1) + 0 if value of cell 8 at time (1 + 1) = value of cell 8 at time 2 and value of cell 8 at time (1 + 1) = (value of cell 4 at time 1) + 0, then value of cell 8 at time 2 = (value of cell 4 at time 1) + 0
5 value of cell 8 at time 2 = 11 + 0 if value of cell 8 at time 2 = (value of cell 4 at time 1) + 0 and value of cell 4 at time 1 = 11, then value of cell 8 at time 2 = 11 + 0
6 11 + 0 = 11 11 + 0 = 11
7 value of cell 8 at time 2 = 11 if value of cell 8 at time 2 = 11 + 0 and 11 + 0 = 11, then value of cell 8 at time 2 = 11
