Abstract

The invention provides a programmable logic device collocation test method. When initializing the programmable logic device, the employed collocation information includes of allocating a specified address and storing a specified value. After system electrifying, this method includes: A. reading the value of the specified address; B. confirming the correction by comparing the reading and the specified value, if wrong, springing the initializing collocation and return to A. With this invention, the collocation correctness can be tested, and the test is not be disturbed by outside.

Description

technical field

[0001] The invention relates to the technical field of detection, in particular to a detection method for programmable logic device configuration. Background technique

[0002] FPGA (Field Programmable Gate Array, field programmable gate array) and CPLD (Complex P Programmable Logic Device, complex programmable logic device) are programmable logic devices, which are developed on the basis of PAL, GAL and other logic devices , Compared with the previous PAL, GAL and other logic devices, it has a larger scale and is suitable for timing and combination design.

[0003] The description of the internal hardware connection relationship of the programmable logic device (referred to as the configuration file) can be stored in a storage unit such as a disk, ROM, PROM or EPROM. After the system is powered on, the configuration file can be written into the programmable logic device for automatic Programming, so when the programmable logic device and peripheral circuits...
