Key Information The automatic invocation of the design-wide performance optimization tool "vopt" has been enabled. Upon invocation, the simulator determines if vopt has been run on the top-level module(s) you supplied; if not, the simulator invokes vopt and outputs a message similar to: # ** Note: (vsim-3812) Design is being optimized... The optimization step will improve run time performance and affect the visibility of objects in the design. To enable debug visibility it is recommended you add additional options to vopt on the vsim invocation via the -voptargs argument. For example: vsim -voptargs="+acc" which enables full debug access to objects in the optimized design. To understand the full usage of +acc and -voptargs, please refer to the chapter "Optimizing Designs with vopt" in the User's Manual for more information. If required you may obtain the previous behavior of vsim, where it does not perform performance optimizations, by setting the modelsim.ini variable "VoptFlow" to 0 (zero). An alternative to setting VoptFlow to zero, where interactive debug compile throughput is required you can use the -novopt option on the vsim and compilation command line (vcom/vlog). The RedHat Enterprise Linux 4 is supported as of the 6.1b release. The support includes the following platforms: 32-bit linux 64-bit linux_x86_64
For a complete list of supported platforms see the Install Guide under the section Supported platforms.
