Proof: Pc 15

Let's prove the following theorem:

if the following are true:
  • instruction #2 is load dst=3 addr=1 imm=1
  • the PC at time 15 = 2

then the PC at time 16 = 3

Given
1 instruction #2 is load dst=3 addr=1 imm=1
2 the PC at time 15 = 2
Proof Table
# Claim Reason
1 the PC at time (15 + 1) = 2 + 1 if instruction #2 is load dst=3 addr=1 imm=1 and the PC at time 15 = 2, then the PC at time (15 + 1) = 2 + 1
2 15 + 1 = 16 15 + 1 = 16
3 2 + 1 = 3 2 + 1 = 3
4 the PC at time (15 + 1) = the PC at time 16 if 15 + 1 = 16, then the PC at time (15 + 1) = the PC at time 16
5 the PC at time 16 = 3 if the PC at time (15 + 1) = 2 + 1 and the PC at time (15 + 1) = the PC at time 16 and 2 + 1 = 3, then the PC at time 16 = 3
