Regarding skill commands

archanav

Hi All,i just started learning Skill scripting for automating the my works in allegro. While doing that i come across two commands for changing the user units. They are as follows below 

axlDBChangeDesignUnits

axlMKSConvert

i want to know the difference between these two. and my current requirement is to change the units from mils/inches/microns/centimeters to millimeters using skill scripting. Could any one help me to do this one ? and one more to thing is how we need to measure the line segments width in the current layer using skill script. 

Thanks in advance for your support.

    Welcome to Skill!

    Use axlDBChangeDesignUnits to change the design units (and accuracy). axlMKSConvert is a mathematical function.

    To measure line segments widths you need to obtain the line segment you wish to measure using axlSelect and axlGetSelSet functions. Line segments have a width property that you can get by using lineSeg ->width.

    There are many examples in your Cadence installation folder in ...\share\pcb\examples\skill. Take a look at these.

    I suggest you take a Cadence Skill tutorial before you dive in. Skill isn't difficult but there are some basics you need to learn.

    You are not in the Skill console so you either need to prefix your commands with "skill " or open the skill console using "set telskill"

    You will find the syntax of commands in in the "Allegro User Guide: SKILL Reference" manual.

    sorry in hurry i forgot to switch into the skill console. Just let me know the way i used the command is correct or not? Because of after jumping into the skill console i am getting error of unbound variable. Could you please let me know how to use this command to get zero error and execution of changing mils to mm in the user inputs.

    You can't just jump into Skill like this and start typing then expect much help here. You need to do some study!

    However, the syntax you want is: axlDBChangeDesignUnits("millimeters" 3)
