The system designs a domain to be full of variable, ensuring signal reachs destination in perfect condition still is an iceberg only one horn. As enclose density to rise ceaselessly, PCB circuitry is refined ceaselessly and ceaseless violent wind rises frequency, these complex issues also are evolving ceaselessly, need uses the professional knowledge of electric, mechanical, electromagnetism and hot kinetic field integratedly.

To answer the complexity that increases increasingly and nuance, the system needs to achieve optimum behavior. And should achieve this one goal, while design personnel is developing intelligence an wisdom, even the computational ability of machine of have the aid of. Regretful is, different course is just as each Gu island each other are detached, block up the effective cooperation between the expert. Want to satisfy the requirement of these increase sharply, systematic level is optimized already was no longer a kind ” extravagant option ” , however ” indispensable ” .

The hand moves working flow to include compose to build, test, archetypal test and verify, improve and make finally, this is optimized to the design created very large block. Current design optimizes a method to rely on the intuition that designs staff greatly, they through founding prototype is mixed move emulate will evaluate a design to whether accord with a target. However, the electronic design nowadays begins to seek stronger performance, taller complexity and more compact external form, the intuition of Chan Ping’s mankind should have been challenged to optimizing hard. We need to optimize a method advancedly to realize increasingly complex contemporary design.

Be based on AI optimize

Cadence rolled out Optimality Intelligent System Explorer, this is optimize a technology brand-newly, use AI to help design personnel answer contemporary design to challenge. This technology has much discipline to design an analysis to optimize (MDAO) function, can not have seam carry out arrive from integrated circuit enclose, and even the systematic level of circuit board is optimized. Tool of analysis of field of will much physics and Optimality Explorer are compositive, ensured anticipate result no risk at all. Automation optimizes a process quickly substantially greatly, engineer and stylist can achieve a goal more easily, more efficiently.

Flow of Optimality Explorer work can appoint input parameter, optimize systematic level, use much physics field to analyse a tool to undertake emulation. It can be finished automatically optimize a process, generate optimize design and final curve. The user can optimize echo loss, insert the parameter such as the loss, segregation that string together faze and eye graph, shake and bit is piled up by accident rate (the system such as BER) standard.

To come true to be optimized effectively, design personnel must consider a line wide, span, line long, pile taking a line, solder dish solder of dimension, segregation dish the geometry such as dimension of geometrical appearance, bore and length of Stub crossing aperture is variable. When establishing a model, still must consider to make Cheng (Process) , voltage (Voltage) and temperature (Temperature) combination, piece inside termination (On-die Termination, ODT) , shake balanced wait for parameter.

Optimality Explorer aims to help design personnel undertake seamed design is optimized notting have, need not user interpose. Its algorithm came true to optimize the automation of the process, can provide fluent, convenient user experience. Compare with traditional method photograph, it can come true to be optimized significantly in the iteration that is less than 500 times, accelerate design astringent. Optimality Explorer is called much discipline analysis and actor chemical industry provide the design synchronism of AI drive.

Optimality Explorer can be emulated well and truly and optimize complex 3D Layout, handle a tradition to go up to be thought to have those who challenge a gender to optimize plan. Include in this tool use at PC to enclose interrelating field to seek solution implement, can handle all sorts of be regarded as to have those who challenge a gender to optimize plan normally, be like the biggest change copper of alternate reseau Fu.

Optimize parameter and note

For example, in systematic communication channel, emitter, receiver, PCB interrelates, enclose and intermediary layer. These parts of an apparatus pass abstraction, use as emitter – the IBIS-AMI model of receiver, emitter – it is to go between receiver line and cross aperture.

To ensure optimal channel function, must consider all sorts of geometry variable, if wide, span, line grows the line, pile taking a line, solder dish solder of dimension, segregation dish dimension of geometrical appearance, bore and length of Stub crossing aperture. When establishing a model, still should consider to make Cheng (Process) , voltage (Voltage) and temperature (Temperature) group, piece inside termination (On-die Termination, ODT) and shake balanced wait for parameter.

In optimizing a process, the design parameter that must appoint need to optimize optimizes a target with what want to achieve. In addition, still must establish additional acting model (Surrogate Model) , with optimizing these parameter effectively.

Optimality Explorer is based on the initiative data set that random search makes, compose is built and training machine learns a model. It can analyse emulation result ceaselessly, newer design is variable, computational target function and tie condition, arrive to stop standard and astringent continuously till.

Optimality Explorer aims to simplify design staff optimize a process, consider in need especially a lot of adjustable below the circumstance of parameter. Its algorithm came true to optimize the automation of the process, need not user interpose, and be used easily.

Traditional method needs the iteration ability of above 2500 times to achieve the result that comparative, compare to it, the iteration that Optimality Explorer needs to be less than 500 times only can come true to be optimized significantly, can accelerate design astringent.

Use Optimality Explorer to improve efficiency

In complex circuit Layout, use only go alone line and crossing aperture is insufficient. Need rises combination of these parts of an apparatus, found interrelate design, among them the behaviour that every parts of an apparatus can affect other parts of an apparatus.

The poor cent between plane of copper of Fu of two across reseau is right

Optimality Explorer can be emulated well and truly and optimize complex 3D Layout, handle the program that optimizes hard on the tradition. Include in this tool use at PC to enclose interrelating field to seek solution implement, can handle all sorts of be regarded as to have those who challenge a gender to optimize plan normally. For example, it is OK utmost ground optimizes poor cent to be opposite the design of copper of alternate reseau Fu in the design, achieve better result thereby. Optimality Explorer still can reduce what detailed scanning place needs to emulate a frequency, achieve a goal quickly.

Before Optimality Explorer can optimize distribution, design with layout hind. For example, optimality Explorer undertakes optimizing to RF power alloter, emulate with 46 only achieved a goal, and enumerate law to need many times 300 to emulate. The versatility of Optimality Explorer still can expand processing has the design of a lot of parameter, for example, optimize the microstrip that has 16 parameter to stick an antenna to need iteration 71 times only.

Look into future: Patulous Optimality platform

The group of backside of Optimality Explorer tool is expanding hard at present the suitable scope of this platform, those who make is OK cover heat and hydrokinetics field. This includes compositive Celsius 3D Solver to be used at heating up an analysis, compositive CFD tool is used at hydrokinetics domain. In addition, electric tie will by compositive the tie government that has to Allegro X Design Platform implement in, offer more comprehensive solution for the user. Develop the newest progress that the group will report these functions are improved ceaselessly.

Drive the much physics field of electronic system to analyse

Solving the high speed signal in modern system to optimize a problem is a challenge that involves many dimension to spend. Optimality Explorer broke through a tradition to go up very the optimizes flow limitation that consumes labor power, replaced with AI drive technology ” design – test – improve ” traditional and alternant flow of the loop, offerred a better system to devise a solution. Optimality Explorer is the beacon of electronic design domain, self-confidence of how-to design personnel moves back and forth at daedal environment, offerring automation technology while improve design efficiency, for integrated design of future the solution levels road.
