Spicy schematics facebook post collection 2012 13 (SWAN applications)Piero Belforte
This document contains a collection of 37 Facebook posts from the page "Spicy Schematics - ischematics.com" from 2012-2013 showcasing circuit simulations and models created using the Spicy Schematics SWAN simulation software. The posts include simulations of transmission lines, cables, amplifiers, oscillators, and digital circuits along with comparisons between different simulation methods. Many of the posts provide simulation results, diagrams, and discussion of modeling techniques.
This document should be very interesting to an engineer because it reports a not biased experimental validation of a predictive tool carried out by a customer for an actual multiboard avionics design. The general considerations are reported at the beginning of the document...the conclusion is that a tool like PRESTO can save up to a 30% in the development time of a system like this . I have other papers reporting validations but these refers to specific non production test vehicules. Then if you give a quick look to the rest of the doc you will have an idea of what is the level of compliance between measurements and predictions...some results are very close together and other shows differences up to 70% or so...but we as engineers we have always to consider the min-max spread of technical specs for digital components may be in order of 100% or more of typical value so it is a nonsense trying to achieve better compliance. Moreover the digital test patterns involved are not the actual ones , and this can make a significant difference, even if Presto was provided with a feature allowing the user to put in the model actual test patterns as input stimuli. Presto was a state-of-the art post -layout tool at this time and this thanks to both the simulation engine (SPRINT, the predecessor of DWS) and to the modeling techniques including PD planes. Extracted nets of up to hundreds of thousands of lines (circuital elements) were simulated in some tens of minutes on machines that were 1000 times slower than today PCs. A true CO-SIMULATION of SI , PI and EMC was performed...no other commercial tool was able to achieve this performance level.
This can give you an idea of the capabilties of both DWS and related modeling methods like BTM ...the PI/SI examples I'm building up for Spicy SWAN are only a very small subset of the complexity Presto was able to deal with.
The document provides a history of Digital Wave Simulator (DWS) from its origins in the 1970s to the present. It details how DWS evolved from early digital wave algorithms developed by the author at CSELT to commercial programs like Sprint and Presto. It describes applications of DWS at companies like Cisco and the development of the THRIS and HiSAFE testing environments. Most recently, DWS has been incorporated into the Spicy SWAN hybrid simulation platform to provide circuit simulation capabilities. Over 500 person-years have been spent developing DWS and its applications for electronic design.
This brochure describes SPRINT, a general purpose circuit simulator developed by Piero Belforte in the late 1980s that was remarkably fast for its time. Belforte notes that SPRINT's simulation speed on workstations from that era would be around 10,000 times slower on modern personal computers, consistent with Moore's Law. Belforte also created the applications presented in the brochure using SPRINT. He later developed Digital Wave Simulator (DWS) based on SPRINT's algorithms to achieve even greater speed performance.
2013 06 tdr measurement and simulation of rg58 coaxial cable s-parameters_finalPiero Belforte
This document compares time domain measurements and simulations of S-parameters for a 1.83m RG58 coaxial cable. Measurements were taken using a TDR setup and compared to simulations using Spicy Swan, MC10, and Cable Studio circuit simulators. Good agreement was found between the measured and simulated waveforms for S11 and S21, though the simulations did not fully capture effects like distributed impedance discontinuities and dielectric losses in the real cable. Optimizing parameters like transmission line delay improved the match between simulated and measured results.
The document details the history of Digital Wave Simulator (DWS), a digital wave analysis simulation software developed by Piero Belforte beginning in the 1970s. It describes how DWS originated from Belforte's work using digital wave algorithms for electrical simulation. Belforte later founded HDT to develop DWS into a general purpose simulator called SPRINT. HDT also created PRESTO for post-layout simulation and collaborated with CSELT to develop THRIS, a hardware qualification tool that became an Italian telecom standard. After HDT closed, Belforte continued independent DWS development through his company SWAN. The document provides links to additional information, applications, publications and the manhours estimated to have been spent

Webinar: Designing a schema for a Data WarehouseFederico Razzoli
Are you new to data warehouses (DWH)? Do you need to check whether your data warehouse follows the best practices for a good design? In both cases, this webinar is for you.
A data warehouse is a central relational database that contains all measurements about a business or an organisation. This data comes from a variety of heterogeneous data sources, which includes databases of any type that back the applications used by the company, data files exported by some applications, or APIs provided by internal or external services.
But designing a data warehouse correctly is a hard task, which requires gathering information about the business processes that need to be analysed in the first place. These processes must be translated into so-called star schemas, which means, denormalised databases where each table represents a dimension or facts.
We will discuss these topics:
- How to gather information about a business;
- Understanding dictionaries and how to identify business entities;
- Dimensions and facts;
- Setting a table granularity;
- Types of facts;
- Types of dimensions;
- Snowflakes and how to avoid them;
- Expanding existing dimensions and facts.
