As a result, the adder chain with pipelines now has a shorter path than the multiplier block by itself.The estimated critical path is now 5.971 ns, which is much smaller than the initial value of 93.872 ns. This
Verilog defparam mydll.mypll_0_0.LOCK_DELAY=500; mydll dll_inst(.CLKI(clkin), .CLKOP(clk1), .CLKOS(clk2), VHDL Not supported For back annotation simulation LOCK_DELAY needs to be set in the preference file. Below is an example for the PLL. ASIC "pll/pll_0_0" TYPE "EHXPLLA"...

https://github.com/verilog-to-routing/vtr-verilog-to-routing/blob/master/ODIN_II/SRC/odin_ii.cpp#L333:L337 . Also he already made a conversion script to get these back. The principle is that Odin puts the clock information within the latch name and the conversion simply takes these and ...
We can describe a multiplier that takes multiple clock cycles to compute its result using a shift-and-add method. The following process, based on an example in the IEEE 1076.6 standard, describes the behavior: MultProc : process is begin wait until rising_edge(clk); if start = ‘1’ then...
The synchronous model of computation divides the program execution into a sequence of logical steps. On the one hand, this view simplifies many analyses and synthesis procedures, but on the other hand, it imposes restrictions on the modeling and optimiza
11.2. ECLKDIV Component Definition The ECLKDIV component can be instantiated in the source code of a design as defined in this section. Figure 11.2, Table 11.1, and Table 11.2 define the ECLKDIV component. Verilog and VHDL instantiations are included. © 2024 Lattice Semiconductor Corp. All...
14. A variable clocking circuit for generating an output clock signal from a reference clock signal, the circuit comprising a variable oscillator: a first clock divider circuit coupled to the variable oscillator and configured to divide the output clock signal by a multiplier M to generate a feed...
United States Patent Application 20160233871 Kind Code: A1 Abstract: In a first clock frequency multiplier, multiple injection-locked oscillators (ILOs) having spectrally-staggered lock ranges are operated in parallel to effect a collective input frequency range substantially wider than that of a ...
