Problems solved by technology
It is suitable for modules with relatively simple functions and protocols. For some complex modules, it is difficult to build a platform, with loose structure, messy architecture, poor code readability, no automatic execution function, and no reusability for different IPs. To a certain extent, it has caused a waste of technology and manpower

The invention provides a module verification system based on an NC system. The first data receiving and comparing unit is used to compare and verify the first type of data to be tested received from the unit to be tested with the preset threshold value of the first type of data to be tested. The control unit is used to generate the comparison and verification results; the second data receiving comparison unit is used to compare and verify the second type of data to be tested by receiving the second type of data to be measured from the unit to be tested with the preset threshold of the second type of data to be tested, and compare and verify The result generation control unit; the third data receiving and comparing unit is used to receive the third type of data to be measured from the unit to be measured, compare and verify it with the preset threshold value of the third type of data to be measured, and control the generation of the comparison verification result unit. The functional coverage and code coverage of the system have met the expected requirements, and the verification environment can be seamlessly integrated into the system verification environment, and the system is applied in the top-level verification.
Description
technical field [0001] The invention relates to the field of node controllers, in particular to a module verification system based on an NC system. Background technique [0002] With the increase of chip scale, verification in chip design has become the most expensive work in the process, accounting for an increasing proportion of the entire design cycle. The workload of verification has accounted for 70% to 80% of the entire SOC research and development, so improving the efficiency of chip verification has become crucial. [0003] Usually based on SystemVerilog test platform, there are five levels. The bottommost signal layer contains the design under test and the signals that connect the design under test to the testbench. The next layer is the command layer, the driver that executes the bus read or write command drives the input of the machine to be tested; the monitor is responsible for detecting the change of the output signal; the assertion passes through the command...
