RTG4
™
FPGAs feature the fourth-generation FPGA fabric with radiation tolerance. Fabric is the programmable
logic section of the RTG4 FPGA, which you can use to congure with VHDL or Verilog. The RTG4 FPGA fabric
consists of the following resources:
•Logic elements: These are basic building blocks in the RTG4 FPGA.
•Embedded memory blocks: These include large SRAM (LSRAM), microSRAM (µSRAM), and microPROM
(µPROM).
•Math blocks: These have a built-in multiplier and adder.
The Libero
®
System-on-Chip (SoC) software (or third-party synthesis tools) automatically infers these logic
elements, embedded memories, and math blocks from the user’s Register Transfer Level (RTL) code. For more
information about the Libero SoC Classic and Enhanced Constraint design ow, see the Libero SoC Classic
Constraint Flow User Guide and Libero SoC for Enhanced Constraint Flow(ECF) User Guide.
The following gure is a top-level functional block diagram of the RTG4 FPGA family. The highlighted fabric block
is described in this document.
