Hi everyone, I am glad to announce the 3.0 release of ForSyDe's implementation, now available from HackageDB. The ForSyDe (Formal System Design) methodology has been developed with the objective to move system design (e.g. System on Chip, Hardware and Software systems) to a higher level of abstraction. ForSyDe is implemented as a Haskell-embedded behavioral DSL (Domain Specific Language).

From this release, ForSyDe includes a new deep-embedded DSL and embedded compiler. We have also published tutorial which should be much more user-friendly than the Haddock documentation and the ForSyDe research papers.

ForSyDe includes two DSL flavours which offer different features: 1) Deep-embedded DSL (ForSyDe.Signal) Deep-embedded signals, based on the same concepts as Lava, are aware of the system structure. Based on that structural information ForSyDe's embedded compiler, can perform different analysis and transformations. o Thanks to Template Haskell, computations are expressed in Haskell, not needing to specifically design a DSL for that purpose. o Embedded compiler backends: + Simulation + VHDL (with support for Modelsim and Quartus II) + GraphML (with yFiles graphical markup support.) o Synchronous model of computation. o Support for components. o Support for fixed-sized vectors à la VHDL. 2) Shallow-embedded DSL (ForSyDe.Shallow.Signal) Shallow-embedded signals are modeled as streams of data isomorphic to lists. Systems built with them are unfortunately restricted to simulation, however, shallow-embedded signals provide a rapid-prototyping framework with which to experiment with Models of Computation (MoCs). o Synchronous MoC. o Untimed MoC. o Continuous Time MoC. o Domain Interfaces allow connecting various subsystems with different timing (domains) regardless of their MoC. o Deep-embedded models can be integrated through simulation.
