Profile: Advanced Layout Solutions Ltd. is a provider of PCB design services to the electronics industry. We meet the requirements of BS EN ISO 9001:2008 quality standard. We provide design solutions covering all aspects of PCB layout from initial feasibility and design right through to manufacture, simulation and testing. We offer three design flows for PCBs. They are standard constraint flow, signal integrity flow and MGHz flow. In standard constraint flow we apply all the necessary high speed physical constraints such as matched lengths/delays, differential pair rules, bus scheduling and characteristic impedance. In the case of signal integrity flow we use pre and post-route simulation to ensure the optimum PCB layout. This flow is suited to high edge-rate designs, especially those that involve DDR memory interfaces, high-speed clock distribution and multi-drop busses. Using the MGHz flow, serial channels can be simulated using channel analysis to predict problems seen on very long data sequences.
