Abstract

Disclosed is a method for automatically generating physical device behavioral shells for use in a digital logic simulator, as well as a from-to wirelist and graphics layout of the device, positioned on a physical modeling adapter card. A program can generate this information from simple physical device characteristics. Such a program eliminates the need for having a skilled programmer create the device behavioral shells. System integrity is enhanced because device placement and orientation on the physical modeling adapter card can be checked and verified. Herein is disclosed a procedure to accomplish automatic behavioral shell generation, a wirelist, and graphics layout of the physical device positioned on a physical modeling adapter card.

Physical Device Behavioral Shell Generation

Disclosed is a method for automatically generating physical device behavioral shells for use in a digital logic simulator, as well as a from-to wirelist and graphics layout of the device, positioned on a physical modeling adapter card. A program can generate this information from simple physical device characteristics. Such a program eliminates the need for having a skilled programmer create the device behavioral shells. System integrity is enhanced because device placement and orientation on the physical modeling adapter card can be checked and verified. Herein is disclosed a procedure to accomplish automatic behavioral shell generation, a wirelist, and graphics layout of the physical device positioned on a physical modeling adapter card. A graphics entry program can obtain device characteristics such as delays, bus pin definitions, package type and pin configuration data (such as input or output pin, logical pin to physical pin correspondence, initial and final pin value states). From the device data the program generates the model language statements necessary to create a program referred to as a physical device behavioral shell. The shell generation program will create the necessary I/O pin definition statements including the combining of individual pin statements into busses. The shell generator will create the statements necessary to send the pin values to the physical modeler whenever an input changes. The shell...
