It is worth noting that it does not change the number of registers when changing the number of registers, ensuring that the logic function expected by the designer is not changed.įanout Guide – one of the Device Mapping Optionsįanout Guide is a global option. Retiming not only changes the position of the register but also the number of registers. Pipelining only changes the position of the register, and optimizes the combination of logic levels between registers by moving the position of the register to achieve the purpose of optimizing the timing. If Retiming is selected, Pipelining will be automatically selected. It is often used in adders, subtractors, etc., and sometimes reduces Reg / LUT slightly. Checking this option allows the compiler to share the arithmetic units in mutually exclusive statements. It is strongly recommended to use "safe" for each state machine, which can automatically reset the state machine to an effective state when it is disturbed and enters an illegal state, to avoid the state machine "dead". Syn_encoding Attribute optional values are "onehot", "gray", "sequential", "safe", "original". Syn_encoding Attribute is used as follows:

Similarly, it can also be designated as a "non-state machine".īTW: The difference between Attribute and Directive is that Attribute is "composite role" and Directive is "compile time role" Attribute is related to technology (such as ALTERA or XILINX, or different series of the same manufacturer), while Directive is not related to technology.

If we want a part of the code to be integrated by the state machine but we have not checked The FSM Compiler option or FSM Compiler does not treat it as a state machine, you can use the above code description to specify it as a state machine. The difference betweenĪnd FSM Compiler is that FSM Compiler is a global option, and syn_state_machine Directive is a local instruction, and the method of use is as follows: It tries three different encoding methods for each detected state machine and selects the optimal encoding method. Checking FSM Explorer will affect the encoding method of the state machine. Checking FSM Explorer will automatically select FSM Compiler. Perform "reachable analysis" of the state machine state to optimize out unreachable states and unexecutable statements. Sequential coding is used for the number of states between 0 ~ 4, One hot code is used for the number of states between 5 ~ 40, and Gray code is used for the number of states above 40.

After checking this option, Synplify Pro will automatically detect the state machine in the code and select different encoding methods according to the number of states. Only give an introduction to the most commonly used options and commands during use.įSM Compiler is a global option. Of course, this article is not intended to be the User Guide of Synplify Pro. However, if you want to use it well, it is not as simple as clicking "Run". It's like telling you "all you have to do is click" Run "". Open its interface, the most striking is a large "Run" button on the upper left side. It contains the BEST algorithm for design Overall optimization. My company is one of them.) The high-performance FPGA synthesis tool provides an excellent HDL synthesis solution for complex programmable logic design.

"New features in the latest releases of Synplify Pro and Synplify Premier software enable FPGA designers to more easily pinpoint design error sources throughout the design hierarchy while improving resistance to radiation effects during operation," Bard said. Synopsys senior director of marketing of solutions group Ed Bard said with SoC designs becoming increasingly complex and many FPGA users requiring greater field reliability, it is vital that methodologies evolve to support robust hierarchical and safety-critical design processes. "As Synopsys expands support for DesignWare, it enables designers prototyping SoCs to more easily integrate their key design functionality into their Xilinx devices," Feist said. Xilinx senior marketing director of design methodology marketing Tom Feist said partnering with Synopsys enables the company to deliver highly integrated design solutions to the benefit of its mutual customers. The newly supported DesignWare Infrastructure IP includes ARM AMBA 3 (AXI, AHB, APB) interconnect, APB advanced peripherals, APB peripherals, microcontrollers (DW8051, DW6811) and memory controller components.
