Altera corporation an 198: timing closure with the quartus ii software the wysiwyg primitive resynthesis option can be used with the stratix™ or the apex™ device families this option is not applicable if native quartus ii synthesis is used with quartus ii synthesis, you do not need to un-map altera. May 2013 altera corporation volume 2: design implementation and optimization perform wysiwyg primitive resynthesis with balanced or area setting the perform wysiwyg primitive resynthesis logic option specifies whether to perform wysiwyg primitive resynthesis during synthesis this option. No related information running the quartus ii software from within the synplify software on page 17-4 synopsys synplify support altera corporation send feedback qii51009 ments, such as wysiwyg primitive resynthesis, which can perform optimizations on your vqm netlist within the quartus ii.
Altera corporation 12–1 may 2008 12 analyzing designs with quartus ii netlist viewers introduction as fpga designs grow in size and complexity technology map viewer shows the hierarchy of atom primitives (such as the figure shows an lcell wysiwyg primitive, with dataa to datad and. Altera, the programmable solutions company, the stylized altera logo, specific device des- ignations performance of its semiconductor products to current specifications in accordance with altera's standard warranty, but reserves the right to make changes to perform wysiwyg resynthesis for area.
Pipelines, including commercial soft processors (nios ii [altera 2015], microblaze [xilinx 2014]) and non-vendor specific synthesizable processors removing the keep attributes and instructing quartus synthesis to allow resynthesis of lcell buffers and wysiwyg primitives this is an inexact comparison, as the desired. A quick idea is check that you have turned on settings-analysis & synthesis netlist optimizations - wysiwyg primitive resynthesis and gate level retiming if design compiler choose poorly these two options might fix it there are also physical synthesis options, but they tend to slow down compiles in.
