Here is the generate-for loop : genvar i; for(i=0; i<7; i=i+1) begin memoire_bit #(.r_switch_on(r_switch_on), .r_switch_off(r_switch_off), .cmem(cmem)) m [7:0] (.vin(vin), .vout(vout), .sample(sample_int[i]), .read(read)); end Whe...
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...

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...
forever loop repeat loop while loop for loop 正文 条件语句if 这个条件语句用来决定是否应该执行某些语句。这与C语言中的if-else-if语句非常相似。如果表达式的值为真,那么第一条语句将被执行。如果表达式的值为false,并且如果存在一个else部分,那么else部分将被执行。
