Abstract
The invention provides a method for supporting a single EEPROM to adjust the driving capability of a plurality of driver chips, which relates to the field of servers and storage. When the system is powered on and started up each time, the software code in the EEPROM can automatically configure the driving capability of each driver chip. Therefore, the purpose of configuring a plurality of drivers by a single EEPROM is realized.
Description
Technical field
The present invention relates to server and field of storage, particularly relate to a kind of method that single EEPROM regulates multiple Redriver chip drives ability of supporting.
Background technology
Along with the development of server and storage products, server and store more and more higher to the functional requirement of product, function quantity gets more and more.When product design, high speed signal is also more and more.Meanwhile, because client requires more and more harsher to product form, the product of various neomorph arises at the historic moment, now, just there will be a large amount of function signals direct interconnected time track lengths exceed the length of standard-required.Therefore, in order to make signal when incoming terminal equipment, signal quality can be guaranteed, and adopts and add Redriver chip in the middle of cabling, signal can be strengthened again after the loss of a segment distance.
In product design, single Redriver chip can not meet all signals usually, needs to strengthen all signals with many Redriver chips simultaneously.If multiple signal arrives same terminal device, and when cabling can not meet isometric requirement, the driving force of each pin position of Redriver chip can be adjusted by software code in editor EEPROM.Although this mode can improve the quality of signal, also can increase the consumption of eeprom chip, bring the increase of cost.
Summary of the invention
In order to solve this problem, the present invention proposes a kind of method that single EEPROM regulates multiple Redriver chip drives ability of supporting.
In order to save the quantity of chip, reduce costs, the present invention proposes: a kind ofly support the method for designing that single EEPROM regulates multiple Redriver chip drives ability.Adopt single EEPROM and multiple Redriver chip interconnect, when system boot, by the software code in adjustment EEPROM, configure the driving force of each pin of all Redriver chips.
The present invention proposes a kind of method for designing that single EEPROM regulates multiple Redriver chip drives ability of supporting.When high speed signal cabling exceeds the length of cabling standard-required, by increasing signal driving chip--Redriver chip strengthens signal intensity, when making signal walk out longer length, can ensure signal quality.When the signal wire of board overlength is too many, and when single redriver chip cannot meet the demands, need the quantity increasing redriver chip can both be guaranteed to the signal quality meeting all overlength signal wires.
Method in this paper is:
Multiple Redriver chip interconnect is got up and to connect with single eeprom chip, will be burnt in same EEPROM to the configuration information of multiple redriver chip; When each system electrification start, the software code in EEPROM can configure the driving force of each redriver chip automatically, strengthens each road signal.So, when the signal through Redriver chip arrives same terminal device, even if track lengths is different, also can guarantee that the signal quality that terminal receives is good
By interconnected for the I2C bus PIN of the I2C bus PIN of EEPROM and each Redriver chip, and I2C bus is connected on a total managing chip.
All address differences being connected to the equipment of I2C bus; When system boot runs, the configuration information in EEPROM can find the equipment of corresponding address according to different addresses, be then implanted in relevant device by configuration information; And the effect of managing chip is burnt in EEPROM by compiled software code, and can according to the test case of signal quality, the code of debugging change EEPROM under machine open state.
Like this, when multiple signal transmits at the same time, isometricly need not synchronously ensure all signal qualitys for signal wire must be walked again.Reduce layout difficulty by the method, reduce EEPROM quantity, reduce costs, improve the quality of products, shorten the R&D cycle, reduce costs.
Accompanying drawing explanation
Fig. 1 is: product P CIE link architecture figure;
Fig. 2 is: Redriver chip drives adjustment rack composition.
Embodiment
More detailed elaboration is carried out to content of the present invention below:
Composition graphs 1, Fig. 2 illustrate performing step, specific as follows:
1), as shown in Figure 1, with the PCIE link of standard, this service condition is described, common server, the PCIE link in CPU all can, when designing, be connected on PCIE slot, to meet different Client applications by the products such as storage;
Such as: client wishes on PCIE slot, equipment such as configuration video card or network interface card etc., but when the profile of board is different, on board, the track lengths of high speed signal is also not quite similar; When PCIE slot distance CPU is very far away, PCIE link from CPU to PCIE slot cabling exceed actual chips require length time, need Redriver chip on adding between CPU and PCIE slot to strengthen the quality of signal, signal can not distortion when arriving PCIE slot to make signal.
Due to the difference of PCIE bus number, a Redriver chip can not meet all signals sometimes.Therefore, the quantity that will increase Redriver is needed.
2) it is in order to same equipment communicates that, all PCIE signal are transferred to PCIE slot.Therefore, the consistance of the signal quality ensureing all arrival PCIE slots is needed.
In order to reach this object, adopt in two ways:
The first: all signal lead to be consistent cabling to PCIE slot, length is consistent, and routing layer is consistent; Then, the driving of all output signals of Redriver is fixed by the configuration PIN of Redriver consistent.Only in this way being only most probable keeps all signal qualitys identical.
The second: do not need strict management and control signal lead length and routing layer, only need increase eeprom chip, by software merit rating mode each pin position of Redriver chip can be configured to different drivings can, like this can according to measure actual signal quality, adjust accordingly.The second way can reduce the difficulty of layout greatly;
3), in order to reduce layout difficulty, and reduce costs as far as possible.An EEPROM is adopted to manage all Redriver chips.
As shown in Figure 2, by interconnected for the I2C bus PIN of the I2C bus PIN of EEPROM and each Redriver chip, and I2C bus is connected on a total managing chip, such as: CPU.
Ensure all address differences being connected to the equipment of I2C bus, this is necessary.Reason is: the software code in EEPROM is the configuration information different according to address assignment.When system boot runs, the configuration information in EEPROM can find the equipment of corresponding address according to different addresses, be then implanted in relevant device by configuration information.And the effect of CPU is burnt in EEPROM by compiled software code, and can according to the test case of signal quality, the code of debugging change EEPROM under machine open state.
To sum up, the difficulty in layout exploitation is reduced by the driving force of EEPROM configuration Redriver chip.Meanwhile, use the Redriver chip that an eeprom chip configuration management is all, reduce the usage quantity of EEPROM.
