QUEST: Frequency-Dependent RLCG Extractor Part 2 – Comparison with Experiments<\/h1>\n

Part 2<\/strong>\u00a0– Comparison with Experiments<\/i><\/p>\n

Introduction<\/p>\n

This article presents a standard case of transmission line: the microstrip structure. First, the structure is described and then the results extracted from\u00a0QUEST<\/i><\/b>\u00a0are compared with measurements. We thank STMicroelectronics (Crolles-R&D) for experimental data support.<\/p>\n

1. Microstrip Structure<\/p>\n

This structure represents a line screened from the silicon substrate by a metallic plate. Figure 1 shows the microstrip structure used for the simulation in\u00a0QUEST<\/i><\/b>.<\/p>\n

The plate and the line are 100 ?m and 4 ?m wide respectively. Though the substrate is screened, it must be defined for simulation purpose. Figure 2 shows the definition of the parameterized materials in\u00a0QUEST<\/i><\/b>\u00a0in the Process menu, whereas Figure 3 shows the mesh parameters in the Field Solver menu.<\/p>\n

The number of Z-slices in the ‘pass1’ layer is adjusted to take into account the skin effect in the metal line.<\/p>\n

2. Results<\/p>\n

In order to compare simulated results with measurements, attention should be paid on the current return path. In\u00a0QUEST<\/i><\/b>, the reference is the substrate by default whereas the experiments have been performed in such a way that the reference is the plate. The default in\u00a0QUEST<\/i><\/b>\u00a0has to be changed by selecting a flag setting the plate as the reference for the current return path.<\/p>\n<\/div><\/section><\/div>
