Traditionally, you should use Sigrity PowerSI or Clarity3D Layout to accurately calculate the electrical properties of a net along with the appropriate post-processing for a PCB design. However, you can use the following simple 2D calculation feature in any Sigrity layout-based analysis tool to quickly get a reasonably accurate total and distributed RLC for a point-to-point signal structure without running simulation.
To achieve this, you can use the Net Electrical Properties function built into the Net Manager window to get all 2D Method of Moment (MoM) results.
Following example has one signal (D2), one power (VCC), and one ground (GND) net defined. The image shows a 3D view for the D2 net only:
The goal is to find the electrical properties from point A to point B.
In the Net Manager window, right-click on the D2 net and choose Property to open the Net Electrical Properties window.
In the Net Electrical Properties window, select Starting Node and Ending Node for a signal trace path and click Calculate to get the electrical properties of the D2 net.

Further to this you can also check the differential impedance of coupled traces in Sigrity layout-based simulation tools like PowerSI. You can find this option in your Edit menu, Go to Edit > Coupled Lines > Manual Setup.
