Steps to run the design using the ise_flow (batch mode): 1. Executing the "ise_flow.bat" file synthesizes the design using XST or Synplify Pro and does implement the design. a. First it removes the XST/Synplify Pro report files, implementation files, supporting scripts, the generated chipscope designs (if enabled) and the ISE project files (if exist any on previous runs) b. Synthesizes the design either with XST or Synplicity c. Implements the design with ISE. 2. After the design is run, it creates ise_flow_results.txt file that will have the ISE log information. Steps to run the design using the create_ise (GUI mode - for XST cases only): 1. This file will appear for XST cases only. 2. On executing the "create_ise.bat" file creates "test.xise" project file and set all the properties of the design selected. 3. The design can be implemented in ISE Projnav GUI by invoking the "test.xise" project file. 4. In Linux operating systems, test.xise project can be invoked by executing the command 'ise test.xise' from the terminal. Other files in PAR folder : * "example_top.ucf" file is the constraint file for the design. It has clock constraints, location constraints and IO standards. * "mem_interface_top.ut" file has the options for the Configuration file generation i.e. the "example_top.bit" file to run in batch mode. * "rem_files.bat" file has all the ISE/Synplify Pro generated report files, implementation files, supporting scripts, the generated chipscope designs (if enabled) and the ISE project files. * "set_ise_prop.tcl" file has all the properties that are to be set in GUI mode. * "ise_run.txt" file has synthesis options for the XST tool. This file is used for batch mode. * "icon_coregen.xco", "ila_coregen.xco" and "vio_coregen.xco"files are used to generate ChipScope ila,vio and icon EDIF/NGC files. In order to generate the EDIF/NGC files, you must execute the following commands before starting synthesis and PAR. coregen -b ila_coregen.xco coregen -b icon_coregen.xco coregen -b vio_coregen.xco Note : When you generate the design using "Debug Signals for Memory Controller" option Enable, the above mentioned ChipScope coregen commands are printed into ise_flow.bat and create_ise.bat files. The example_top rtl file will have the design debug signals portmapped to vio and icon ChipScope modules. * At the start of a Chip Scope Analyzer project, all of the signals in every core have generic names. "example_top.cdc" is a file that contains all the signal names of all cores. Upon importing this file, signal names are renamed to the specified names in "example_top.cdc" file. This file will work for the generated designs from MIG. If any of the design parameter values are changed after generating the design, this file will not work. For Multiple Controller designs, signal names provided in CDC file are of the controller that is enabled for Debug in the GUI. synth folder: 1. mem_interface_top_synp.sdc 2. script_synp.tcl 3. example_top.prj 4. example_top.lso mem_interface_top_synp.sdc and script_synp.tcl files are being used by Synplify Pro and example_top.prj and example_top.lso are being used by XST.
