May I know how to write rule for the fillet polygon


Dear Support Team,
May I know how to write the rule for the fillet calculation, the fillet radius =3u .

and the spacing between the 2 fillets or polygon to the fillets.
I try to write calculating angle, but was not able to get the code correct,
Spacing = ≥ 5um
fillet radius =3u

anglelim = 80 # Angle above which
tol = 0.2 # General Width/Space Tolerance (to allow for curves), in um
lay1.width((3-tol).um, projection,
angle_limit(anglelim)).output("lay1 Min Width 5um")
lay1.space((5-tol).um, projection,

May I have your support and guidance pls. thanks in Advance.

  • Sorry, I don't understand.

    You want to apply fillets? Or you want to check something with fillets? Could you please explain the rule you're trying to check?

    Hello Matthias,
    I want you to write the DRC rule for the fillets drawn,
    the specification of the fillet,
    Spacing = ≥ 5um
    fillet radius =3u
    I tried writing DRC rule blew to check the violation but not able to highlite the violations.
    anglelim = 80 # Angle above which
    tol = 0.2 # General Width/Space Tolerance (to allow for curves), in um
    lay1.width((3-tol).um, projection,
    angle_limit(anglelim)).output("lay1 Min Width 5um")
    lay1.space((5-tol).um, projection,

    Kindly let me know for any clarifications.

  • There is no specific check for detecting fillets with a specific radius, I'm sorry.

    Spacing is easy to check, but filled radius is something that is not implemented.
