Proof: Pc 19

Let's prove the following theorem:

if the following are true:
  • instruction #6 is store src=3 addr=1 imm=0
  • the PC at time 19 = 6

then the PC at time 20 = 7

Given
1 instruction #6 is store src=3 addr=1 imm=0
2 the PC at time 19 = 6
Proof Table
# Claim Reason
1 the PC at time (19 + 1) = 6 + 1 if instruction #6 is store src=3 addr=1 imm=0 and the PC at time 19 = 6, then the PC at time (19 + 1) = 6 + 1
2 19 + 1 = 20 19 + 1 = 20
3 6 + 1 = 7 6 + 1 = 7
4 the PC at time (19 + 1) = the PC at time 20 if 19 + 1 = 20, then the PC at time (19 + 1) = the PC at time 20
5 the PC at time 20 = 7 if the PC at time (19 + 1) = 6 + 1 and the PC at time (19 + 1) = the PC at time 20 and 6 + 1 = 7, then the PC at time 20 = 7
