met layer
metSpacing: CD.DesignNumber = 3 * CD.lambda; -- Metal spacing
metWidth: CD.DesignNumber = 3 * CD.lambda; -- Metal width
metCutViaSpacing: CD.DesignNumber = 0 * CD.lambda; -- Cut to Via spacing

m2 layer
m2Spacing: CD.DesignNumber = 4 * CD.lambda; -- Metal 2 spacing

These numbers are half of the actual minimum distances we are checking for.
