Please use "upload image" option available in the post to share the snapshots of your results for helping us serve you better. As Ansys employees we cannot access the attachments across the forum.
Coming to your question. The simulation and solving methodologies in both HFSS and 3D layout are one and the same.
HFSS is mostly used for fully arbitrary 3D models where as 3D layout is specially used for models which have very slight thickness.
You should get similar results provided the models to be same.
Please go through the this video on 3D layout which may help you Cosimulation Using HFSS 3D Layout and Circuit - Lesson 3 - ANSYS Innovation Courses.
All the very best.

H─░ Thank you for reply. I am sharing screen short of results. The results have three graphs. The red one is for the planarEM setup, green is for HFSS setup ( These both are obtained through ) HFSS layout tool while the blue one is for the result achieved by using HFSS 3D tool. As you can seen non of results are matching .

Result achieved through CST are more resembling to planerEM

[Praneeth]

I suspect that the difference in results may be because of the differences in the simulation setups.
Are you using cosimulation with circuit and pushing the excitations into the models?
If so, can you check whether the excitations are set properly?
Best regards.

No I am not using co simulation . For PlanerEM setup and HSFF setup in layout are exactly same. I have import the dxf file and used edge port to excite it obtained Planer EM solution and HFSS solution without changing any thing
