One of the great feature that comes along with ADS Package is the ability to create your design in a reverse flow. This necessity become more evident when you prefer to use other feature-reach layout tool than ADS and use ODB++ or ADFI tools afterward to import the design into the ADS for performing layout…
Understanding the math behind length matching of each protocol is a key in reaching out a well designed PCB with a balance between performance and layout area and other manufacturing constraints. Unfortunately for some protocols such as SDIO these information remained under NDA’s and are confidential. Here I examined ZC702 reference design board and/or datasheet…
I know that there exist many disperse app note around how to export pin delay and why you should do that nevertheless I can’t find any comprehensive guide line which accompany you from A to Z of this process so I convinced to wrote down this post. For DDR3 and other sensitive high speed signals…
Inserting via in RF and Microwave regions might seems to be a scary thing to do but as revealed through EM simulation for low portion of Microwave frequencies (below 10GHz) using a full via isn’t as worse as it seems to be. From “full via” I mean a via that start from top layer and…
ADS Momentum is a full-wave EM field solver that merged with ADS package for more than 10 years. Starting with the ADS 2016.1, two new tools introduced by Keysight, the SI and PI Pro environment that can be accessed through layout interface inside the ADS software. In this post, I’ll talk about features of these…
Cadence and Keysight are collaborating with each other since 2000’s which brings one of unprecedented feature to reality, an ability to export your design from allegro to ADS seamlessly. In this tutorial I will demonstrate how to configure Allegro Design Flow Integration (ADFI) for Allgero 17.2 and ADS 2017 Update 1. I am aware that…
I use AutoHotkey in almost all my application but I notice some Qt applications (Like ADS) had some difficulty interpreting the AHK keys correctly. The problem turns out to be affiliated with UAC and Admin rights rather than the Qt library. To solve the issue simply add following lines to the top of your AHK scripts…
State The Problem This is a bug I found in many versions of Xilinx Vivado package and I actually now struggling with it in 2017.2 version. I don’t check out newer versions so it maybe already been solved, idk! Anyway, in my version on the Linux platform, if you open the SDK normally and then…
Lately DDR3 is becoming more prevalent in new custom designs however I find that there isn’t much comprehensive document available for newcomers to the DDR franchise. Here I wrote down my own bootstrap on learning DDR3 jargons and way up to design and understand underline rationale behind the DDR3 length matching. Why DDR The first…
One of the great feature of XInput is “Mouse Wheel Emulation” that I graceful with it for more than 5 years. Lately I notice it relieve my hand If I could trig wheel emulation by a key on keyboard instead of a mouse button. Unfortunately up to this time Evdev not support that and pushing a…
