This topic provides a high-level overview of the new features in the IC23.1 release.
IC23.1 ISR3
Virtuoso Visualization and Analysis XL now supports plotting of Pulse-Amplitude Modulation 3-Level (PAM3) eye diagram. PAM3 is a digital signaling technique (modulation scheme) that uses three voltage levels. It offers a good balance of power efficiency, robustness, and complexity. It is well-suited for various applications, such as high-speed data communication systems and optical networks. New measurements, Tmid and Tmid Height, Threshold, Threshold Width, and Eye Amplitude, can be performed using the Eye Diagram assistant.
You can also calculate the ​peak-to-peak jitter values for the left and right corners of the eye.
SKILL function:
A fixed-y marker is a special point marker attached to the trace at the specified y-axis value. You can display a y-level indicator when a fixed-y marker is selected, and drag it vertically to change the y position of the marker. A new tab, FixedY, has been added to the Create Graph Marker form. You can specify the fields on this tab to add a fixed-y marker on a trace. You can also use the bindkey Shift + Y to add a fixed-y marker.
If you send a trace that contains parametric sweep data to Virtuoso Visualization and Analysis XL Table (Table), sweep variables are displayed as headers of the Table.
