Data simulation apparatus and data simulation method

A data simulation apparatus, comprising:

• a programmable logic device configured to implement at least one interface protocol, to send and receive simulation data and test data respectively according to the at least one interface protocol, wherein
• the simulation data comprises first data and second data, and
• a transmission rate of the first data is lower than a transmission rate of the second data;
• at least one first interface configured to connect the programmable logic device and at least one first device under test, to transmit the first data and the test data;
• at least one second interface configured to connect the programmable logic device and at least one second device under test, so as to transmit the second data and the test data,
• a disk array connected to the programmable logic device in communication and configured to store the simulation data and the test data;
• and
• a cache array connected to the programmable logic device in communication and configured to read and write data for the disk array;
• wherein the disk array comprises at least one disk, the disk comprises at least one sending channel sector and at least one receiving channel sector, the sending channel sector is configured to store the sent simulation data, and the receiving channel sector is configured to store the received test data;
• wherein the cache array comprises at least one cache element, the cache element comprises at least one sending channel buffer and at least one receiving channel buffer, the sending channel buffer is configured to read data from the sending channel sector, and the receiving channel buffer is configured to write data to the receiving channel sector;
• and
• wherein each of the first interface and the second interface is allocated with an independent sending channel sector and an independent receiving channel sector.
