OK, let's go one step further. What if I replaced 'assign' with 'always_comb'?

The following example would not be considered legal. module test(output logic [3:0] out, input [3:0] in, input [0:1] idx); for (genvar I = 0; I < 4; I++) assign out[(idx+I)%4] = in[I]; endmodule ________________________________ From: owner-sv-bc@eda.org [mailto:owner-sv-bc@eda.org] On Behalf Of Bresticker, Shalom Sent: Thursday, March 30, 2006 6:35 AM To: sv-bc@eda.org Subject: [sv-bc] FW: question: continuous assignments to variables Hi, I never got a response to this. Shalom ________________________________ From: Bresticker, Shalom Sent: Monday, February 27, 2006 1:57 PM To: sv-bc@eda.org Subject: question: continuous assignments to variables Hi, In 1364, if the LHS of a continuous assignment is a select, the select needs to be a constant select. 1800 says that the LHS of a continuous assignment can be a net or variable of any data type. For a net, the BNF net_lvalue still seems to restrict that to constant selects, but the text does not seem to mention that restriction. It probably should, because one might interpret "any data type" as relaxing that restriction. But mainly, I want to ask about variables as LHS of a continuous assignment. I don't see that the BNF (variable_lvalue) restricts it to have a constant select. Is that true? If so, why is there a difference between variables and nets?
