Description
Technical field
The present invention relates to Ethernet technology, particularly relate to a kind of test macro and the method for ethernet device jockey and application thereof.
Background technology
Ethernet has auto-negotiation ability, and auto-negotiation is to realize by a kind of signal that is called quick connection pulse, and the both sides of auto-negotiation carry out swap data by quick connection pulse.In the situation that possess the port of auto-negotiation ability, do not have to connect, port can send quick connection pulse always, and the concatenation ability information that is comprising oneself in connecting pulse fast comprises the speed, duplex, Flow Control of support etc.If both sides support auto-negotiation, all can receive the other side's quick connection pulse, and the information decoding in a quick connection pulse out, thereby obtain the other side's concatenation ability, then separately according to own and the other side's maximum concatenation ability, select best connected mode to connect.Such as, if both sides had both supported that 10,000,000 also supported 100,000,000, speed connects according to 100,000,000, once after connecting, connect fast pulse and just stop sending.
In addition, in order to guarantee also to connect in the situation that a side can not support auto-negotiation, introduced the mechanism of parallel detection, a side, opened auto-negotiation, the opposing party closes in the situation of auto-negotiation, and establishment of connection just relies on parallel detection function to realize.
So-called parallel detection mechanism is exactly, have on the device port of auto-negotiation ability, if do not receive quick connection pulse, detect the characteristic signal that whether has 10,000,000 links or 100,000,000 links, if detecting is 10,000,000 equipment, do not support auto-negotiation, on link, send generic connectivity pulse, generic connectivity pulse only indication equipment is in place, does not comprise other extraneous information.If detecting is 100,000,000 equipment, do not support auto-negotiation,, in the situation that there is no data, on link, can send the idle code stream of 4B/5B coding always.Based on above principle, when a side does not open auto-negotiation, a side who opens auto-negotiation can only consult into semiduplex mode.
Current chip manufacturer can provide testing tool or test instruction to realize to allow equipment under test from output data line, send the idle code stream of the required 4B/5B coding of test.But the testing tool that chip manufacturer provides normally uses under the operating system of Windows, for having the equipment under test of Windows operating system, some just cannot not use; The test instruction that chip manufacturer the provides Input Software code that need to go down at the environment of running software, for personnel that are not familiar with software, operates not too convenient.And no matter be that testing tool or test instruction all need to look for each different chip manufacturers help to provide, relatively lose time.
