3. Design Decisions Wiring Conventions were modified
Metal 1 is used for all basic gates
Metal 2 used horizontally
Metal 3 used vertically
Metal 4 used for global routing (clk and rst)
Decided to go with a Line Decoder, transistor count changed from 1043 to 303
Minor design changes for each functional block

23. Gate Schematic Verification
Initial Conditions: age = 12,temp = 69, body = 0
safetywatch = x
ascensionwatch = x
ascensionwatch = 0
safetywatch = 0
Now the diver is going to go straight to depth=100 and stay for 20 minutes
At the end of that segment: timeleft = 144, timefly = 415, maxdepth = 100,bottomtime = 18, pres=21
Now the diver is going to go straight to depth= 40 and stay for 15 minutes
ascensionwatch = 1
At the end of that segment: timeleft = 194, timefly = 669, maxdepth = 100,bottomtime = 32, safety = 0, pres=24
Now the diver is going to go straight to depth= 0 and stay for 40 minutes
At the end of this segment: timeleft = 248, timefly = 669, maxdepth = 100,bottomtime = 32, safety = 0,pres=15
Now the diver is going to descend at a rate of a foot a second for 50s, initial depth = 0
At the end of this segment: timeleft = 118, timefly = 669, maxdepth = 100,bottomtime = 33, safety = 0
Now the diver is breifly going to descend at a rate of two feet a second, initial depth = 50
At the end of this segment: timeleft = 75, timefly = 669, maxdepth = 100,bottomtime = 33, safety = 0,pres=15
Now the diver is going to ascend at a rate of two feet a second for 10s, initial depth= 56
At the end of this segment: timeleft = 165, timefly = 669, maxdepth = 100,bottomtime = 33, safety = 0,pres=15
Now the diver is going to ascend at a rate of one foot a second for 25s, initial depth= 36
