Output port selection, cable connection scheme are completed in hardware assembly.Software configuration complete emulation input/output signal and
The matching of hardware output port configures.
Hardware assembly is related to the position of simulation card and simulation card ID, it is contemplated that the bus that each board exports includes
Many different signal wires, are not suitable for customization, therefore, the mode of connection in every bus is consistent.By the way of reasoning
Hardware assembling scheme is solved, rule is the simulation card that every two has input and output connection relationship, needs to meet interconnection
Connector mouth it is consistent with hardware output end slogan, further infer between board line rule.It is complete to obtain
