Intel FPGA Language-Neutral LibrariesCategory : Simulation/VerificationThis option enables Aldec customers with VHDL only license to simulate the most recent Intel FPGA Libraries without purchasing a separate Verilog license (which is required as some of the design units written in Verilog/SystemVerilog). In order to leverage this option, VHDL only customers must request Intel FPGA Simulation Libraries from Aldec at www.aldec.com/support/customer_portal.
