When running post syn esis simulation, all defined packages are supplied to ModelSim. Since a file defines bo package and sub-module, e post syn esis simulation fails because e sub-module is defined twice. i.e. in e package file and in e syn esized netlist. Solution/Workaround: Work-Around. e pre-syn esis simulation results in ning messages (similar to ose above) for any instantiated sequential components. is is due to mismatches in e timing arcs of e simulation library introduced by e components package files in Libero v2.3 or Designer R1-2003. o er syn esis tool, and VHDL simulator softe. Chapter 3 - Generating Netlists contains information to allow you to generate a netlist using Synopsys, ACTmap, or o er syn esis tool. Chapter 4 - Simulation wi MTI V-System or Model Sim contains information and procedures about simulating for Actel. 5 Introduction is VHDL Vital Simulation Guide contains information about using e Model Technology V-System or ModelSim, Mentor Graphics QuickHDL, Cadence NC-VHDL, Viewlogic SpeedWave, and Synopsys VSS to simulate designs for Actel devices. Actel makes no ranties wi respect to is documentation and disclaims any implied ranties of merchantability or fitness for a particular purpose. Information in is document is subject. e Actel Quick Start Guide for Libero IDE contains information for using e Libero IDE softe to create designs for, and program, Actel devices. is manual includes information about e Libero IDE softe, which allows you to generate and/or import a netlist generated from a ird-party CAE tool, perform pre-syn esis simulation. e Actel HDL Coding Style Guide is divided into e following chapters: Chapter 1 - Design Flow describes e basic design flow for creating Actel designs wi HDL syn esis and simulation tools. Chapter 2 - Technology Independent Coding Styles describes . Feb 25, · Compile Simulation LibrariesFPGA simulation libraries should be compiled before doing post syn esis or post PAR simulationFPGA simulation libraries contains definition of logic components used in e simulation modelCompiled FPGA simulation libraries are independent on e simulated design and can be used as much as e FPGA. In Libero e default entity name for e test bench is 'testbench'. As a consequence when ddc is root and if you run a post syn esis simulation, Libero outputs in e do file run.do as follows: vsim -L postsyn -t 1ps postsyn.testbench. add wave /testbench/*. When performing post-syn esis and post-layout simulation in ModelSim, customers observe ‘unknown’ signals in eir design. However, ese signals are defined in pre-syn esis simulation. Symptoms: is problem usually affects components such as registers, counters, state machines, etc. Laser Range Finder Using Actel's Axcelerator FPGA 7 Post-Layout Simulation After design implementation is completed, verify at your design meets timing specifications by performing e post-layout simulation. Figure 8 illustrates best-case conditions, and Figure 9 on page 8 shows e same simulation under worst-case conditions. Running post syn esis and post layout simulation of a design wi package files. Description: When you run post-syn esis simulation, all source files are not passed to Modelsim. Only syn esis/top_level.vhd is passed along wi testbench.vhd. If e top level file and testbench uses package file en simulation will fail. in an Actel FPGA is ree 2:1 MUXes and an OR gate). Try doing at using traditional techniques, and you'll see at pen-and-paper succumb to e almighty syn esis tool. at doesn't mean at you don't have to ink anymore, however. e issues wi in digital design using FPGAs and syn esis tools wi VHDL are different, but just as critical. Create a new directory tree called \Actel\Vlog\src in your ModelSim installation directory. Copy e source library you downloaded from e Actel website into e src folder you just created. 2. Post-Syn esis Simulation vlib work_postsyn vmap work./work_postsyn. Actel designs using HDL syn esis and simulation tools. Design Flow Illustrated Figure 1-1 illustrates e HDL syn esis-based design ﬂow for an Actel FPGA using ird party CAE tools and Designer softe. 1. Actel-speciﬁc utilities/tools are denoted in black in Figure 1-1. Design Creation/Verification Silicon Explorer Data I/O System. Actel's customers have come to expect e best in FPGA syn esis over e years, said Jim Davis, Vice President of Softe and Systems Engineering at Actel. Synopsys is a valued, best-in-class supplier, and we are very pleased to be able to continue to . In PLL simulation (pre-syn, post-syn and post route) some output frequencies do not show up as expected. .. 20 38. Post-syn esis and post-layout simulation gives invalid results for e INOUT bus. Step 3 - Design Syn esis/EDIF Generation A design must be syn esized if e design was created using VHDL or Verilog. Use Synplify or Synplify Lite from Synplicity to generate your EDIF netlist. You can re-verify your design post-syn esis using e VHDL or Verilog ModelSim for Actel simulator used in step 2. While all RTL code must be. Invoke e ModelSim for Actel simulator by double clicking e ModelSim for Actel Simulation button in e Libero IDE Process window or by selecting example1 in e Libero IDE Design Hierarchy tab en right clicking and selecting Run Pre-Syn esis Simulation (Figure 15). Note: if you ran 2. 3. Window and select Run Post-Syn esis Simulation. e ModelSim for Actel Verilog Simulator will open and compile e source file and e testbench. When e compilation completes, e simulator will run for 1 us and a Wave window will open to display e simulation results. Scroll in e wave window to verify e counter works correctly. Libero SoC generates a gate-level VHDL netlist from your EDIF netlist for use in post-syn esis pre-layout structural simulation. e file is available in e /syn esis directory if you wish to perform simulation manually. Structural Simulation Perform a structural simulation before placing-and-routing. HDL code line by line. Designers can perform simulation at all levels: behavioral (or pre-syn esis), structural (or post-syn esis), and back-annotated, dynamic simulation. (ModelSim is supported in Libero Gold, Platinum, and Platinum Eval only.). e VHDL Vital Simulation Guide contains e following sections: Chapter 1 - Setup contains information about setting up ModelSim and Cadence VHDL simulator. Chapter 2 - Design Flow describes how to use e VHDL design flow to design an Actel device using e syn esis . Lab 5: VHDL Syn esis to FPGA In is lab you will: design a chip containing a traffic light controller, using VHDL (submit a state diagram) perform functional simulation wi out circuit delays. use Actel Actmap softe to syn esize a netlist from e VHDL code targeted for an FPGA. for e RTAX-S from e beginning to e end. Actel’s Designer softe generates e fuse file for e commercial Axcelerator prototype device (Figure 1).

I am making a design for an IGLOO FPGA from Actel and I have have added a Two Port RAM component in Libero (e development tool). Here I can choose to Customize RAM Content and have imported an Intel Hex File. is works perfectly in simulation, but not post-syn esis and layout simulation. For e post-syn esis VHDL simulation you need to comment e following lines in e vhdl netlist generated just after syn esis: for all: A7SUse entity work.A7S(DEF_ARCH). e Component Base Address in e generated Memory Map is correct but some of e Register descriptions not correspond wi e information in e relevant Datasheet. 3.
