Support for SystemC Support for Verilog 2001 Third party tools integrated with FinSim(Specman, Denali, Debussy, Undertow, Vera, VirSim, HDL Score, Comet, Meteor, NelSim, Pivot, DeskPOD, @Designer 2.1)		FinSimMath for mathematical descriptions within Verilog 1. FinSim's support of FinSimMath is described in chapter 8 of FinSim's User's Guide, which you can also download as a .pdf file  . 2. A detailed example of transforming a scalar productt into the corresponding FIR Filter is shown in Integrating FinSimMath in an Existing Design Flow.pdf   . FinSimMath includes: Variable Precision Fixed and Floating point representation, modifiable during the execution of the simulation. Cartesian and Polar predefined types. Separation of data from its location for multi-threading processing. Matricial operations including overloading of +,-, *, /, and ** for all supported types (i.e. real, cartesian, polar, fcartesian, fpolar). Support for solving differential equations. Support for FFT, DCT. Finding roots of polynomials and finding the polynomial given the roots. Finding the rank of a matrice. Finding the characteristic polynomial of a matrix. Finding the eigen values and eigen vectors of a matrix. Finding a feeback matrix that places poles where wanted. Solving systems of liniear differential equations. Support for arithmetic, trigonometric and hyperbolic functions. Support for sparse matrices. Support for distances between matrices and for norms of matrices, including sparse matrices. 2. Download the FinSimMath Tutorial as a .pdf file  The tutorial presents an introduction to FinSimMath and provides several commented examples that run on the FinSim Verilog simulator. 3. FAQ about FinSimMath Numerous questions about FinSimMath are addressed in here. 4. Using FinSimMath DSP designers can determine the optimal sizes and formats for the operands used, by modifying sizes and formats during the execution of the simulation FinSimMath capabilities are shown at work in this Butterworth IIR LP filter application. 5.
