PTC Mathcad vs. Siemens Valor

It is great for any manual calculation. You can lay it out as you would on paper, but the math is calculated instantly, similar to how it is in excel. It is superior to either method for most engineering calculations. Being able to copy-and-paste is very helpful for considering multiple scenarios. In some situations where you need to do the same calculation on an array of numbers, Excel is still faster.

• Conversion of measurement units (Imperial and Metric)
• Easy to use for writing detailed engineering worksheets
• Formulas can be written in the expanded form which facilitates verification
• Spell Checker feature is life saver.

• VPL: component info from Siemens library server, component management.
• NPI: integration with Xpedition Designer.
• Easy to install and configure Valor.

• Some of the math and text formatting aspects are a little cumbersome.
• Converting from older Matchcad versions to the newer Mathcad Prime platform could be made easier. It should be a direct import function.

• Valor NPI licenses: we are working with Siemens to resolve the issue that Siemens doesn't check out the "command-line" Valor NPI Xpedition license when running Valor checking from Xpedition Designer.
• Valor Process Prep: we discovered a defect in the product. Currently waiting for a fix.
• Rule checking: Too many false positives.

Higher-order math, despite symbolics, become tedious and variable nomenclature isn't as forgiving as other programs. Due to it's sheet-like nature, the greater the complexity the more bothersome the screen usage becomes. But it's a trade-off between a sketchpad-like interface or lines and lines of code. Pick your poison but MathCad was our choice.

MathCAD is easier to learn and faster to start with. It has more user-friendly interface and conventional style toolbox and GUI. It is really good for the beginners and those who are afraid of complex math.
