Abstract

The invention discloses an ICE (In-Circuit Emulator) automated test system and an ICE automated test method. The test system comprises two major parts including an upper computer and a lower computer, wherein the upper computer uses a script as a central control board of the test system; the lower computer comprises a DUT (Device Under Test) and a TB (Test Board); and the upper computer communicates with the lower computer through an API (Application Programming Interface). According to the automated test system and method, digital function testing of all ICE supported models can be realized, labor input of testing is reduced, manual operation is reduced to a great extent, and a test process is greatly shortened; and a test log is automatically output, so that test personnel can quickly discover problems and repair chip design.

Description

technical field

[0001] The invention belongs to the technical field of automatic testing, in particular to an automatic testing system and method for an on-line emulator based on a field programmable array. Background technique

[0002] An in-circuit emulator (ICE), also known as a hardware emulator, is a physical device equivalent to a chip used in the MCU development process. The characteristics of its products are to strictly approximate the functional characteristics, electrical characteristics and physical characteristics of real chips. Using the device and its supporting IDE development environment, users can quickly perform embedded programming, cross-compilation, real-time simulation debugging, etc. Such devices generally have reconfigurable characteristics, that is, an ICE can usually simulate the characteristics of multiple MCU chips.

[0003] However, with more and more chip types compatible with ICE, product testing has become an extremely heavy workload. Beca...
