The System Generator Design Flow 11
Introduction
The System Generator design flow is shown in the following figure.
Figure 1-1: System Generator design flow diagram
The Xilinx Blockset is accessible in the Simulink library browser, and elements can be
freely combined with other Simulink elements. Only those subsystems denoted as
Xilinx black boxes, and blocks and subsystems consisting of blocks from the Xilinx
Blockset are translated by System Generator into a hardware realization. The
generation process is controlled from the System Generator block found in the Xilinx
Blockset Basic Elements library. The System Generator parameterization GUI allows
the user to choose the target FPGA device, target system clock period, and other
implementation options.
System Generator translates the Simulink model into a hardware realization by
mapping Xilinx Blockset elements into IP library modules, inferring control signals
and circuitry from system parameters (e.g. sample periods), and converting the
