Design methodology

Insight SiP’s methodology is based on a user extendable library of physical objects for which the electrical models are created automatically for a given stack-up and/or technology. Thus any design that is initially made for a particular supplier can easily be re-tuned for an alternative source. The method uses a combination of circuit and EM simulations to create a design progressively from basic schematic representation to a complete layout.
2.5D or 3D EM simulations are used for the passive integrated functions (laminate, IPD, LTCC, PCB) and harmonic balance or device modeling for the active circuits. The functionality that is contained within buried functions inside the substrate is created using an iterative process.

- First step:
It is to create for a given technology a range of parameterized mechanical objects.
These objects allow simple RF functions, such as capacitors, inductors and resonators, to be created. - Second step:
It is to couple the technology file for the target process to the mechanical objects.
A series of batch based electromagnetic simulations of the mechanical objects within the desired technology file framework creates data for a look-up table based model for each component (L, C or more complex resonator element).
It allows for the creation of a set of project and technology related schematic objects that can be optimized to produce the required RF functionality.
Simulations using these models can be carried out in both the frequency domain and the time domain. At this level of the design, circuit optimization is carried out to determine the parameters of the schematic/mechanical object. This process is quite similar to that carried out in semiconductor design using library based objects that have electrical performance and create layout. - Third step:
The third step of the process is to create complete sections of physical layout with the mechanical objects using the circuit optimization parameters.
A closed loop iterative process is used to obtain final layout that has the same electrical performance as the sum of the modelled portions. At this stage coupling effects between blocks are compensated for. This has the advantage of allowing the mechanical objects to be placed close together without any risk of causing unseen effects. This makes the designs created by this method more compact than those using a “P Cell” approach with large keep-out zones to avoid coupling.
