Welcome to Advanced Layout Solutions!

Since our foundation in 1995, Advanced Layout

Solutions Ltd (ALS) of Aldermaston, Reading has

completed over 4,800 printed circuit board designs.

We can offer you a complete package that is second to

none, from initial feasibility study, through PCB desig

and onto volume manufacture for your products.

you are considering outsourcing PCB design-related

services, you need look no further.

What’s Different at ALS?

Recognising the importance of performance in today’s

high-speed designs, we operate three individual design

flows, each flow representing a different balance

between PCB design and signal integrity analysis.

These flows, shown below, give us the flexibility

handle the most complex of products, without over

engineering simple designs.

Seven Key Benefits of Using ALS…

► We are the only PCB bureau to be expert in both board design AND signal integrity analysis. Using our advanced design-flows we can VERIFY your design at an early stage, leading to fewer board iterations and reduced risk of failure.

► Our familiarity and experience with the latest technologies provides an extensive knowledge base from which your company will benefit.

► As the largest independent Cadence bureau in the UK, we have the capacity to be flexible and highly responsive, with the ability to service your needs at very short notice.

► Our expert-level tools and staff mean you can expect faster turnaround times. This reduces time-to-market, helping you maintain your competitive edge.

► Designs are completed on schedule so you can rely on meeting a known budget for your project, thus avoiding cost overruns. ► Our working practices are approved to ISO9001:2000 and our staff and facility are cleared for secure work, including government contracts. ► We can provide a complete service from

design to manufacture and test, providing a

"one-stop shop" for clients who want to

maximise the benefits of outsourcing.

Design Tools

At ALS we use the state-of-the-art ‘Silicon-Package-

Board’ tool set from Cadence Design Systems,

including Allegro PCB Editor and Allegro PCB

SI. We provide schematic capture for both the

Design Entry HDL and CIS front end tools

(AKA Concept and OrCAD) and offer library

creation/managenent services for both.

We have the ability to import netlists from virtually

any front-end design tool, including all Mentor tools

(PADs, DxDesigner, BoardStation) and other third-

party tools (Zuken, Altium, CADstar, etc.) We can

also translate in-progress or completed Mentor PCB

designs into Cadence format, for completion or

signal integrity analysis.

Quality

We pride ourselves on the consistent quality of our

designs, and this is reflected in both our

accreditation to BS EN ISO 9001:2000 and our

government clearance to undertake secure contracts.

The high level of support and service throughout

each and every project is just one reason why our

clients return again and again.

Constraint Management

To achieve a successful PCB

embedded ‘constraint management’

extensive experience in this area allows us to apply the

appropriate constraints to ensure your designs work on

the first iteration. The Constraint Manager built into

Allegro allows us to constrain

from propagation delay to crosstalk voltage, and

provides a cockpit from which constraints can be

entered, analysed and signed off.

Signal Integrity Analysis

Developing constraints often requires simulations to be

run early on in the design process

transistor-level modelling tools we are able to carry out

analysis of your designs, even prior to schematics being

generated. We have the tools and skills necessary to

identify signal integrity issues EARLY in the design flow

saving our customers both time and money.

To verify that the actual routing meets signalling

requirements, post-route simulations can be run to

ensure that a product is not likely to suffer from

unforeseen effects caused by vias, connectors or

traces.

MGHz Serial IO With 3.125Gbps+ IOs common in off-the-shelf

FPGAs, it’s no surprise that we are seeing an

increasing number of our customers integrating this

technology into their designs. ALS is able to accurately

model MGHz links by using transistor-level

HSPICE transceiver models – and implement

multi-gigabit data channels that are free from board

level signal quality issues.

Using the latest design tools we are able to accurately

extract PCB interconnects and model them in the

frequency domain using S-parameters.

Latest PCB Technologies

Thanks to an impressive list of technology-leading

clients, we have great exposure to the latest PCB

technologies and fabrication techniques, including

stacked-microvias and specialist materials. Our broad

experience with these technologies has given us a great

understanding of the benefits they offer, as well as the

pitfalls to avoid!

Deliverables

Quality is at the heart of everything that we do. For

this reason all our finished designs are verified with

Valor Enterprise and output in ODB++ format to

ensure that your products enjoy trouble-free

manufacture.

Working Together

Good communication between clients and layout

designers is the key to your success. ALS hosts

online meetings and can share the designer's

desktop with all parties involved in a project to

significantly speed up the design-review process.

The client has real-time access to the design,

without the need for costly CAD software. This

web-based approach has allowed ALS to develop

closer relationships with their clients, no matter

where they are based.

At ALS we adopt a strategy that is appropriate for

your project. When time-to-market becomes your

key requirement we can provide fast turnaround

times on even the largest of designs by using a

multi-designer methodology, thus avoiding the

‘PCB layout bottleneck’.
