TLM Simulation 12Workshop - November 2011
MAGILLEM Tool RTL Level: - Bus interface, components creation, link between components: ditto TLM. VHDL code generation: - Using generics. - The code is readable by an individual. - Inter-connects are taken into account during the VHDL code generation. 13Workshop - November 2011
GAUT Tool The C code: - The C code must be very close to VHDL code. Comparison with commercial tools: - Roccc, ImpulseC. Some troubles during VHDL code generation: - The generated code can be synthesizable but it does not work well in placement/routing. 14Workshop - November 2011
IP-XACT Advantage Standard: Reuse strategy Support of SystemC Model by TLM ports Opportunities for “bottom up” and “top down” XML Transformation: correct and complete XML descriptions Hardware description: lot of data for several components 15Workshop - November 2011
