Radiation_Medium is the objects that don't meet Radiation_High or _Low.
Radiation_High is Clock or other nets that have very fast switching edges. Radiation_Low has contant nets or reset nets.
I'm not sure how the properties are set in CES. But anyway, you can override the CES influence with the followin ways:
1. When you import design data, delete (or rename) .cicd file. xxx.cicd contains properties from CES.
2. Or, on HL DRC, from the menu, Setup > Options > Constraint Manager > select "First time design loaded".
Then, you can change settings. Otherwise, data came from CES are read-only.
Please note you can change this setting only prior to load a design.
Another way is to copy the rule and paste it to a new rule group. You can assign a new object list for this new rule.
(You need to create a new object list that contains objects you want to check.)
Hope this helps,
You said that Radiation_High is clock or other nets that have very fast switching edges but I want to know how is it set this property. For instance, in this example, to know if a net has a very fast switching edge you should indicate this parameter and also the frequency of the net in any place, no? The question is where? In the DxDesigner schematic?
I know that there are another ways, as copying the rule and pasting it to a new rule group and then assign a new object list for this new rule, but I would know if I can change only the assignations to Radiation_Medium changing some parameters in the PCB or indicating anywhere.
For instance, the column Frecuency (picture below) is set to 1GHz to all my nets because it is the default value of HL DRC (Setup - Options - Default Values) but I want to change/import according to a specific attribute in the schematic (for example). It is possible? I know that I can change it manually in the HyperLynx DRC changing the corresponding value (as in the picture below) but this is not the idea.

Radiation and Susceptibility are defined through the followin steps:
1) If a net is contant, then Radiation class=low, Susceptability class=low
2) If a net is clock, then Radiation class=high
3) If a net has model pin marked as Oscillator, then Radiation class=high
4) If Radiation class is unassigned at this point, then Radiation class=medium
If Susceptibility class is unassigned at this point, then Susceptibility class=high.
A net is considerd a clock net if it is included into classified object list "ClockNets"
By default, the filtering condition is as below:
As I explained here, the setting doesn't come from DX or CES.
(We read some attributes/properties/assigned IBIS model in CES.)
