Witryna3 cze 2015 · Synthesis tools usually come from a vendor such as an FPGA vendor, and they translate arbitrary code into that vendor's logic gates, not yours. The ideal solution is to create a library describing your logic technology, which plugs into a vendor-neutral synthesis tool, such as Synplicity from Synopsys. Then Synplicity can synthesise to … WitrynaLOGIC GATES IN VHDL VHDL allows for the specification of Boolean functions based on the following gates: AND, OR, NOT, XOR, NAND, and NOR. EXAMPLE: Write the VHDL code to implement the following circuit whose output is ‘F’: x F C B A y • Note: In VHDL, A B C are inputs (IN), F is an output (OUT), and x and y are internal signals …
