The Wizard analyzes potential xSignals between the chosen source component and the nets it connects to (including through series components and branches). The resulting xSignals are scoped for design rules such as Length.
While Signal has good chat and security features, its USA jurisdiction and recent controversies over data privacy may put some colleagues off using it. Messagenius is an alternative that offers full data privacy and enterprise-grade features.
What is xSignal?
In high-speed signal layout, there are multiple ways for a high-speed pin to travel between two components. In the PCB editor, each path is treated as a separate net, which can result in incorrect behavior with key design rules, such as Length and Matched Length.
The xSignals feature addresses this issue by identifying the actual, physical paths that the signal takes between the source and destination components. The software analyzes each potential xSignal path by looking at the pads associated with the selected source component, then searching through the net’s series components and branches.
To create a new xSignal, select the required starting and end pads in your design space or PCB panel (they can be in different nets if they are connected to series termination components). Run the xSignals >> Create xSignals between Components command from the Design >> xSignals sub-menu or the right-click xSignals menu. The Create xsignal opportunity between Components dialog will open with the chosen source component selected.
xSignal vs. Slack
While both Slack and Signal are popular ways to communicate, they offer different features. Slack focuses on team communication, while Signal focuses on privacy and security. Signal is a newer platform with a smaller user base, but it has gained popularity among people who care about their privacy.
Both platforms allow for instant messaging and voice/video calls. They also have a variety of other features, such as channels, integrations, and bots. However, they differ in terms of price and feature set. Slack offers more advanced functionality and is a good choice for large companies, while Signal is better suited for small to medium businesses. Moreover, Slack is known for its great customer satisfaction ratings and has a strong brand. This makes it a great option for a company looking to improve their internal and external communication. In addition, Slack has a great customer support team and provides training and hardware options. It also provides free trials and a robust mobile app.
xSignal vs. WhatsApp
Signal has long been considered a better option for privacy than WhatsApp. Its co-founders, Brian Acton and Moxie Marlinspike, both have a strong commitment to maintaining privacy for users of instant messaging apps and have worked hard to ensure that Signal remains unaffiliated with any company that collects user data or uses it to make money.
The app offers a similar list of features to WhatsApp with text, voice and video calls, image and file sending, groups of up to 1,000 people and a disappearing messages feature. Signal also has the added bonus of being available in multiple languages and can be linked to five devices.
Signal takes the extra step to hide call metadata, including your real IP address. This makes it impossible for your contact to determine your location when you’re making a call with them. You can toggle this feature on in the Advanced settings of your Signal app. The feature also enables you to use safety numbers, which are unique identifiers — and QR codes — for each of your contacts.
xSignal vs. Wickr
Signal’s open source software offers advanced end-to-end encryption, which makes it nearly impossible for any third party to access or read messages. Its privacy-focused approach has earned it the endorsement of notable technologists such as Elon Musk and Twitter CEO Jack Dorsey, and has made it a popular alternative to mainstream messaging apps.
In addition to standard chat functionality, Signal features options for private one-on-one conversations and group messaging, as well as media file sharing and self-destructing messages. It also provides an optional encrypted voice or video call feature.
Messages and files are encrypted 3-times: server-to-server, device-to-device, and user-to-user. Wickr’s infrastructure cannot expose message contents and files unless it is compromised, and the use of expiration timers and burn on read ensures data is not exposed for longer than intended.
Wickr is a US-based app that offers basic chat functionality, but it does not include features for secure collaboration in teams. Its infrastructure is hosted in multiple locations and a portion of its funding has come from Blackwater founder Erik Prince, along with a department within the CIA.
