Definitions
- the present invention relates to a semiconductor inspection apparatus, and in particular, by combining a semiconductor device to be inspected (hereinafter referred to as LSI) and simulation data on a computer implemented in the design stage, the present invention relates to the related art Is related to a semiconductor inspection device that can easily realize various inspections, evaluations and analyzes that were difficult to realize.
- LSI semiconductor device to be inspected
- simulation data on a computer implemented in the design stage
- SoC System On Chip
- the conventional LSI tester When performing a functional test of an LSI equipped with these many asynchronous circuits, the conventional LSI tester has many limitations, and therefore, it operates on various products on which the LSI to be tested is mounted. It has become difficult to realize completely.
- An LSI tester applies an input signal to a test target LSI (hereinafter referred to as DUT: Device Under Test) in order to execute a desired operation.
- DUT Device Under Test
- This input signal corresponds to the OZ1 digital data stored in the pattern generator in the waveform mode specified by the format controller and the voltage V and current according to the signal change timing specified by the timing generator.
- the functional test of the DUT is performed by comparing the output signal from the LSI to which the input signal is applied with the OZ1 expected value pattern stored in the pattern generator. At this time, the output signal from the DUT is determined by the digital comparator at the strobe position specified by the timing generator and whether the OZ1 determination voltage condition set in VOH is satisfied or not.
- Input signals and output expectation values are generated according to a cycle-based test table called a test pattern (also called a test vector).
- a test pattern also called a test vector.
- the test pattern under test execution is stored in the pattern generator or attached pattern memory.
- LSI testers are called cycle-based test systems, and are defined in various cycles (test rates, timing sets) corresponding to various data forces for generating the input signals and output expectation values. It is done.
- HDL hardware description language
- VHDL Verilog or VHDL
- function description data hereinafter referred to as “higher abstraction level”
- RTL logic circuit data
- netlist logic circuit data
- Test pattern creation uses simulation data used in logic verification performed on the designed RTL and netlist. In the simulation, a test pattern is created by using data input to the designed circuit as an input signal of the test pattern and capturing an output from the designed circuit as an expected value of the test pattern.
- simulation results for example, VCD: Verilog Value Change Dump
- WGL waveform generation language
- STIL standard test interface language
- the simulation generally performed in the logic verification is an event-driven type as opposed to a cycle-based type such as an LSI tester
- the simulation is performed as described above. Even if you convert the result, it does not reflect the concept of the LSI tester such as the waveform mode and test rate, and it is difficult to use it directly with the LSI tester. Therefore, it is necessary to convert simulation results into cycle-based format first, convert it to WGL or STIL format, and convert it to test pattern format dedicated to LSI tester.
- Patent Document 1 proposes an event-type IC test system for the purpose of reducing the enormous number of work steps for creating such a pattern. Treating simulation data in the process of large-scale SoC development as an event file requires a considerable amount of work. The reason is that the actual large-scale SoC simulation environment simulates an environment in which LSI is actually used (hereinafter referred to as a set environment), which is not the test environment with LSI testers.
- the microcode is transferred from the external flash memory 201 in which the microcode is stored to the SR AM 202 in the SoC 200 through the external memory interface 204, according to the microcode Assuming that the SoC 200 is designed to operate, in the inspection environment, it is necessary to delete the external flash memory 201 and create an event for inputting microcode to the external memory interface 204. Further, in the case of a specification in which the work DRAM 203 is connected to the external memory interface 204, it is necessary to create a data transfer event with the DRAM 203 in the inspection environment.
- Patent Document 1 JP 2005-525577
- the maximum operating frequency that can be set by the clock generator is defined. That is, a clock higher than the maximum operating frequency output from the clock generator can not be applied even when the maximum operating frequency of the DUT is higher. Therefore, in testing using an LSI tester, the maximum operating frequency can not be guaranteed.
- the problem is that even when using an LSI tester that has an output function of a high-speed clock such as 1 GHz, for example, when asynchronous operation becomes complicated, the asynchronous operation is completely reproduced. This is also the case when the maximum operating frequency can not be guaranteed because it is difficult. This is the same even if the maximum operating frequency of the DUT is 1 GHz or less.
- the timing of the transition point in each cycle is the same if the clock is 1 to the power of 2 with respect to the maximum operating frequency of all input signal strength testers. Therefore, it becomes possible to express with the above-mentioned test pattern, and there is no problem. Of course, it is possible to express similarly for data input synchronized with the clock which is only clocked.
- simulation data used in test pattern generation is data used in logic verification, in the case of a circuit including many asynchronous circuits, the input and output signals are naturally asynchronous. .
- simulation uses an event-driven input pattern that is not cycle-based, such as an LSI tester. If data from such asynchronous event-driven simulation is directly converted into test patterns, it will result in high-speed and long patterns, as described above, and patterns that can not be used with LSI testers. There is sex.
- test patterns created by such cycle-based synchronous simulation tools are different from the conditions for logic verification, and are also different from the conditions under which LSI is actually used, so sufficient quality can be ensured. It is difficult to say that it is a level test pattern.
- the object of the present invention is, as shown in FIG. 4, to actually use an LSI to be tested by directly diverting data of an event-driven asynchronous simulation used in logic verification to an LSI tester. It is an object of the present invention to provide an LSI tester capable of realizing high-quality inspection with less man-hours, which enables inspection under conditions as much as possible and significantly reduces the number of man-hours for creating test patterns.
