Synplify pro component name full#

And as a result, synplify handles initial blocks and inline initializers differently from FPGA tools - specifically, it mostly ignores them, even if it causes strange, unexpected behavior. For ASICs, it's common to not initialize anything, ever, and instead use explicit resets. Synplify is intended for synthesizing designs for ASICs, not FPGAs, and as a result is rather opinionated. The Go Board uses an external crystal for the clock.

The full project is actually up on GitHub.Д®DIT 2: I also understand that a PLL Lock signal could be used as a power-on reset, but unfortunately the HX1K does not have any PLLs. And because Lattice can only initialize registers to 0, I want to use a power-on reset signal to set X/Y to non-zero values. I'd like the ball to start in the middle of the screen, not at (0, 0). The reason it does this is because ball_absolute has a pair of X/Y registers for the ball's position on the screen. The o_rst of this reset_generator component is hooked up to another component at a higher level like this: wire w_reset So why does the first version get optimized out? And why does adding an initial value that gets ignored change the behavior? Is this just a quirk of iCEcube2 and/or Synplify Pro?Д®DIT 1: I'm using a power-on reset because Lattice can only initialize registers to zero, and I'd like some to start off with non-zero values. This warning also implies that initial values are 0. Now it no longer is getting optimized out and works as expected, but iCEcube2 shows this warning: : reset_generator.v(13) | User-specified initial value defined for instance reset_gen.rst_count is being ignored. However, if I explicitly set rst_count to 0, like this: reg rst_count = 0 I thought all registers were initialized to 0, so I'm not sure why it thinks rst_count is always 1. ICEcube2 outputs this warning: : reset_generator.v(13) | Register bit rst_count is always : reset_generator.v(6) | Input i_clk is : ball_absolute_mv_vga_top.v(19) | Removing instance reset_gen (in view: work.ball_absolute_mv_vga_top(verilog)) of type view:work.reset_generator_4s(verilog) because it does not drive other instances.ДЄnd I can verify that the o_rst signal is indeed never set to 1. If I write the the module like this, it is getting optimized out: `default_nettype none I am synthesizing using Lattice iCEcube2 + Synplify Pro targeting an iCE40 HX1K on the Nandland Go Board. When you edit a component, the class name and pathname are both displayed, in the basic information at the top of the Components editor window and in the Basics tab.I am trying to write a Verilog module that generates a power-on reset signal for a few clock cycles. When you select a component in the Components window of the ATG Control Center, the class name is displayed in the Bean Information panel at the bottom of the ACC window.

The Components window can also help you limit this confusion. Maintaining good package structures and clean development environments right from the start always helps avoid such problems. For example, the class might be instantiated as a component called /services/Scheduler. This confusion becomes even more pronounced when the component name is the same as the class name, as often happens when there is a single instance of certain components in an application. For example, a Java file for the class is supposed to live at /services/log/fileLogger.properties. For both types of files, the fileвЂ™s position in the namespace also determines its position in the file directory. The confusion usually arises when a developer starts writing all of the Java source files and properties files required to build an application. It should also be clear that two components in Nucleus cannot have the same absolute name, but they may have the same class. This is probably not very confusing - a component in Nucleus has both a component name and a class name. In the previous section, for example, a component of class Person was constructed into a component called /services/Person. When you work with Nucleus components, it is essential to remember the difference between class names and component names.
