However, the values in those columns are all "NA". The enclosed IBIS file has "NA" for all min and max values, yet the parser gives the following warnings: WARNING - Model 'IO': MIN VI curves cannot drive through Vmeas=2.5V given load Rref=500 Ohms to Vref=0V WARNING - Model 'IO': MAX VI curves cannot drive through Vmeas=2.5V given load Rref=500 Ohms to Vref=0V INSERT IBIS FILE DEMONSTRATING THE BUG: [IBIS Ver] 2.1 [File Name] nocolumn.ibs [File Rev] 0.1 | |*************************************************************** | [Component] TEST [Manufacturer] Test File [Package] | variable typ min max R_pkg 0.0m NA NA L_pkg 0.0nH NA NA C_pkg 0.0pF NA NA | [Pin] signal_name model_name 1 One_Pin IO | |*************************************************************** | [Model] IO Model_type I/O | Vinl=1.5V Vinh=3.5V Vref=0V Rref=500ohms Cref=50pF Vmeas=2.5V | |variable typ min max C_comp 8pF NA NA [Voltage Range] 5V NA NA | [Pulldown] |voltage i(typ) i(min) i(max) -5.000V -672.6mA NA NA 1.277V 171.8mA NA NA 10.000V 171.8mA NA NA | [Pullup] |voltage i(typ) i(min) i(max) 10.000V -397.0mA NA NA 3.003V -179.2mA NA NA -5.000V 437.3mA NA NA | [Ramp] |variable typ min max dV/dt_r 3.93/851p NA NA dV/dt_f 3.93/718p NA NA R_load = 500Ohms | [End] ****************************************************************************** ******************** BELOW FOR ADMINISTRATION AND TRACKING ******************* ****************************************************************************** BUG NUMBER: 21 SEVERITY: [FATAL, SEVERE, MODERATE, ANNOYING, ENHANCEMENT] ANNOYING PRIORITY: [HIGH, MEDIUM, LOW] LOW STATUS: [OPEN, CLOSED, WILL NOT FIX, NOT A BUG] CLOSED FIXED VERSION: 2.1.15 FIXED DATE: January 30, 1998 NOTES ON BUG FIX: ****************************************************************************** ******************************************************************************
