Choosing the best software for high speed PCB design requires more than just designing in an efficient and quick way available. One needs to take into consideration the connector, memory module and every processor and carefully understand the interconnection between them.

Choosing a software means picking a product to be used in the modern world and this requires pushing design techniques and boundaries of PCB technology. It is not an easy task and care is needed. When it comes to choosing a software for PCB design, a number of factors need to be taken into consideration.

Need for an extra eye: The engineer who does the layout and the designer are usually not the same. Therefore it is important to have the layout technician consult the first designer to ensure the software is suitable. Co-ordination between the two creates a continuous stable product since each of them understand what is required. Poor connection between the two may lead to a host of many challenges throughout the process.

Parasitic: High speed circuitry is an advantage in creating a product. The disadvantage with high speed circuits is their potential to being impacted by stray. It is important to understand the source of the stray and how to avoid it. This will ensure no sudden instability interferes with the design.

Shielding: The signals usually interfere with each other and in cases of high speed circuits, the effects are evident. Such conflicts may not be good for the design. Therefore, the PCB designers need to plan accordingly to ensure the board can avoid such interferences. There are a number of techniques used to implement this depending on the layout.

Detailed schematics: To have good layout for high speed PCB design, there is need for a detailed schematic form. Although concerns are always raised concerning the physical layout, a detailed schematic saves time in answering questions by having the exact desired flow of circuit. Information like component placements, board housing and trace lengths should be available.

Major components location: The major components need to be well-designed for proper board functionality. The location of input points, outputs, and power locations can have an impact on the general performance of the PCB. Placement of individual sockets is required to ensure that their proximity does not affect the functioning of another.

Bypassing Power supply: The aim of bypassing is to minimize noise and this ensures high speed. The common tricks used include rail-to-rail and rails-to-ground to experience quality results. The aim of bypassing is to increase efficiency of the software. Simple interruptions can slow down the process making it ineffective.

Initial plans: Successful high speed designs are ones planned properly from the start. Any small mistake at the beginning can lead to many complications later on. You need proper tools for managing and designing constraints starting with the memory specification to other information needed for efficient design. Spreadsheet is useful in setting design constraints.

To ensure proper designs, set up the constraints from the beginning and use them throughout the process. First the rules and constraints created in the schematic stage should be synchronized with the PCB to ensure the design follows the specifications. Ensuring easy management of the complex designs hierarchy and other structures for the high speed circuitry.

The two Johnstone Pipe Bands and Renfrewshire Schools Pipe Band travelled to Gourock at the weekend for the local Highland Games.  On a mostly fine day weather-wise all three bands had decent starts to the season with the Schools band coming third in the Novice Juvenile B Grade in their first outdoor event.  The Grade 4 band won both of their competitions at that grade and also best drum corps in what was a fine performance.  The Grade 1 band also came third in their competition as they gear up for the British Championships this coming Saturday in Paisley.

Pipe Major Keith Bowes Jr commented, “I am delighted with how our bands from Renfrewshire performed at the first outdoor competition of the season. Our brand new Renfrewshire Schools performed extremely well, considering how young and inexperienced they are to the pipe band scene. The grade 4 band continue to improve and perform well, continuing on their success from last year, and the grade one performed well with an improved standard which I hope reflects the hard work we have put in over the winter months. All three bands did our association proud and I wish them all the best for the rest of the 2017 season.”

TODDLERS had a marathon session of fun and laughter in the longest ever Bookbug session held at Paisley Central Library.
To celebrate Bookbug Week, Renfrewshire Leisure staged a Gigglethon in the library on Monday.

The theme of the Gigglethon was humour and children under the age of five, along with their parents or carers were invited to come along any time during the day to have some fun and a good laugh.
And everyone at the Gigglethon was given a free book, mask and sticker courtesy of the Scottish Book Trust.

The event, at Central Library is just one of several fun sessions being held in libraries and venues throughout Renfrewshire to celebrate Bookbug’s Big Giggle.
Joyce McKellar, chief executive of Renfrewshire Leisure said: “Our libraries are really fun places to go all the year round, but the marathon Gigglethon was extra special.”
Log on to for more information about Bookbug Week sessions locally.

Paisley will be invaded by a tartan army on Saturday when more than 4,000 of the world’s best pipers and drummers descend on the town for the British Pipe Band Championships.

Mark F Gibson / Gibson Digital –

The St James Playing Fields will again host one of the most prestigious events on the world bagpiping calendar, as part of the push towards Paisley’s bid to be UK City of Culture 2021.

More than 140 pipe bands from as far afield as Canada, Denmark and Ireland will compete in the day-long event before judges from the Royal Scottish Pipe Band Association (RSPBA).

Mark F Gibson / Gibson Digital –

The event is free to attend and a crowd of thousands is expected – the event arena opens at 10am, with the final march-past and prize-giving to take place around 5.30pm.

Attractions on the day include a bar, as well as a food market with a focus on quality Scottish produce from farm to fork, and the Slug in a Bottle craft market.

Free activities include a Highland dancing competition and children’s entertainment zone including giant inflatables, face painting and sporty fun with the team behind Renfrewshire’s Street Stuff Culture Bus.

This year’s chieftain is Renfrewshire charity champion and quadruple amputee Corinne Hutton – who has helped hundreds of people through her Finding Your Feet charity.

There will be no parking at the site – other than for pipe band coaches – but free shuttle buses will run to and from the free event parking sites at the Paisley 2021 Stadium (Greenhill Road) and West College Scotland (Renfrew Road).

There will also be a free shuttle bus running to and from Paisley Gilmour Street station (Old Sneddon Street entrance) for anybody arriving in town by train. All three shuttle buses run every 15 minutes from 8am to 7.30pm.

Paisley 2021 Bid Director Jean Cameron said: “We are thrilled to welcome the British Pipe Band Championships back to the town for the second of its three-year run here.

“Events like this are important for the UK City of Culture 2021 bid as it shows Paisley has the infrastructure and know-how to host large-scale events.

“Our visitors from throughout Scotland and abroad will be guaranteed a warm welcome in the town.”

Ian Embelton of the RSPBA added: “We are pleased to be back in Paisley for another year and delighted to have another huge turnout from bands.

“Everything is in place for a day of top-class competition and I am sure the piping community and visitors alike will find plenty to enjoy.”
