Firstly, thank you for reading. I have a similar question, but this time, I reference a Virtuoso schematic instead of another AMS. Following Andrew's suggestion, I add a dummy instance outside of the generate loop. Then I can see the cell I want to reference in Hierarchy Editor. I set...
If I unrolled the generate block loop manually (which is very painful!), the simulator runs fine. I tried to instantiate a dummy SINE block outside generate loop to make config view pick it up (which it did), but I got the same error. Is there ...
然而for循环的开头和结尾都是明确的,由步骤变量控制。 module my_design; integer i = 5; initial begin for (i = 0; i < 5; i = i + 1) begin $display ("Loop #%0d", i); end end endmodule 1. 2. 3. 4. 5. 6. 7. 8. 9. 仿真结果: Loop #0 Loop #1 Loop #2 Loop #3 Loop...
SystemVerilog added the ability to put the genvar inside the for loop. Verilog-2005 made the generate/endgenerate keywords optional. The compiler should be able to tell from the context whether the for-loop is a generate-for or a procedural-for. I would try removing them and seeing if you...
Sequential statements for state assignments should only contain reset values and a next-state to state assignment, use a separate combinational-only block to generate that next-state value. A correctly implemented 8-bit register with an initial value of "0xAB" would be implemented: 👍 logic foo...

可以把你出错的那段贴出来看看，这样更详细。这个意思应该是指在generate循环条件里，使用了不和语法的非常量
