Abstract

Disclosed is a method for verifying the function of a microprocessor based system. This method is unique because no components need to be manufactured to verify the function. It differs from simulation in that operation of the system is within one decimal order of magnitute of the intended target system frequency.

Functional Verification of a Microprocessor-Based System without
Manufacturing Components

      Disclosed is a method for verifying the function of a
microprocessor based system.  This method is unique because no
components need to be manufactured to verify the function.  It
differs from simulation in that operation of the system is within one
decimal order of magnitute of the intended target system frequency.

      This method is implemented using 2 distinct products.  The
Enterprise* and RPM* systems are used to emulate the function of
integrated circuits under development.  FPIC** technology is used to
create an interconnect environment for all system components.

      The intermix of logic emulation with system interconnect
technology yields a prototypal environment.  In this environment, the
function may be verified by operating the system in a manner similar
to the intended application.

      The logic emulation is prepared by providing a technology
dependant netlist to the emulation software.  The software consumes
this input, partitions the design into a system of reprogrammable
logic devices, and the prepares the program for each device.  The
input and output signals for each integrated circuit are identified,
and the interface to the target environment is defined.

      The system interconnect mechanism is prepared by providing a
schematic representation of the system in a wiring list format.  The
interconnect software will then lay...
