| ****************************************************************************** | 3.1 drivesch 0.1 7/16/98 | The following model demonstrates the use of IBIS multistage driver | schedules to describe an inverting and non-inverting model | with pulsed turn-off of the pullup transistor in an output | stage. In this example, during pullup cycles the pullup driver | is turned on at time=0 and then turned off at time=10ns. The pulldown | driver is always on during the pulldown part of the cycle. | | ************************************************************************** | Driver-Schedule Manufacturer Name | 0ohms 0H 0F | 1 1 10ns_Non-Inverting 2 2 10ns_Inverting | | ************************************************************************** | 10ns_Non-Inverting 0.9 1.1 1.00 0.00p 25.00 1.50 | 1.25pF | 1.5V | | Nchan 0 0.21n Pchan 0 10n | | The clamping data is used here for the receiver mode of the I/O buffer | | (It was moved from the Pchan model) 2.998V 0A -1.178V 100uA -1.22V 0A -1.242V 1.4mA -1.257V 2.6mA -1.268V 4.09mA -1.277V 5.94mA -1.285V 8.27mA -1.291V 10.59mA -1.297V 13.58mA -1.303V 17.41mA -1.309V 22.31mA -1.315V 28.6mA -1.321V 36.66mA -1.327V 47mA -1.333V 60.24mA -1.339V 77.23mA -1.345V 98.99mA -1.348V 110mA -1.35V 120mA -1.354V 140mA -1.357V 160mA -1.365V 222.547mA -1.372V 300mA -1.375V 340mA -1.379V 400mA -1.387V 560mA -1.392V 690mA -1.397V 850mA -1.4V 960mA -1.406V 1.24A -1.412V 1.58A -1.418V 2.03A -1.425V 2.71A -1.431V 3.48A -1.437V 4.46A -1.443V 5.72A -1.449V 7.33A -1.45V 7.64A | | The following model data is replaced by the models in the driver schedule | | 1.498mV 0A -300mV 0A -301mV 0A | 0V 0A 150mV 21.59mA 406mV 56.34mA 699mV 91.6mA 788mV 100mA 962mV 114.286mA 1.07V 121.645mA 1.237V 132.251mA 1.507V 150mA 1.981V 150mA | 631.08mV 1.86ns 631.08mV 1.86ns 25ohms | | ************************************************************************** | | 10ns_Inverting 0.9 1.1 1.00 0.00p 25.00 1.50 | 3.28pF | 1.5V | | The following model data is replaced by the models in the driver schedule | | | The following model data is replaced by the models in the driver schedule | | 1.498mV 0A -300mV 0A -301mV 0A | 0V 0A 150mV 21.59mA 406mV 56.34mA 699mV 91.6mA 788mV 100mA 962mV 114.286mA 1.07V 121.645mA 1.237V 132.251mA 1.507V 150mA 1.981V 150mA | 631.08mV 1.86ns 631.08mV 1.86ns 25ohms | | ************************************************************************** | | Nchan 0.9 1.1 1.00 0.00p 250.00 1.50 | 3.28pF | 1.5V | | | Table is VCC relative 1.499V -0A -480mV -0A -481mV -0A | 0V 0A 150mV 21.59mA 406mV 56.34mA 699mV 91.6mA 788mV 100mA 962mV 114.286mA 1.07V 121.645mA 1.237V 132.251mA 1.507V 150mA 1.981V 150mA | | 698.4mV 888ps 698.4mV 1.47ns 25ohms | | | 25ohms 1.5V 0s 334.17mV 105ps 353.96mV 212ps 454.06mV 317ps 513.42mV 528ps 712.47mV 836ps 1.09659V 925ps 1.18389V 1.057ns 1.26537V 1.184ns 1.34103V 1.332ns 1.41669V 1.48ns 1.49817V | | 25ohms 1.5V 0s 1.49817V 159ps 1.49468V 203ps 1.48769V 270ps 1.44579V 409ps 1.25373V 613ps 863.79mV 779ps 648.45mV 907ps 485.49mV 980ps 468.03mV 1.387ns 394.7mV 1.634ns 378.4mV 2.041ns 351.63mV 2.247ns 344.64mV 2.45ns 334.17mV | | ************************************************************************** | | Pchan 0.9 1.1 1.00 0.00p 25.00 0 | 3.28pF | 1.5V | | | Table is VCC relative 1.501V -23.76mA 919mV -22.43mA 499mV -19.69mA 249mV -16.74mA 32mV -12.96mA -163mV -8.62mA -368mV -3.23mA -479mV -28uA -481mV 32uA | 0V 0A 2V 0A | | 337.09mV 144ps 337.09mV 1.32ns 25ohms | | | 25ohms 0V 0s -22.98uV 48ps 5.6mV 96ps 531.45mV 240ps 561.79mV | | 25ohms 0V 0s 561.79mV 99ps 541.57mV 200ps 381.45mV 299ps 57.28mV 400ps 538.93uV 700ps -22.89uV 2.101ns -22.89uV 2.2ns -22.89uV | | | | **************************************************************************
