我试图初始化一个模块数组，它们每个都有3个参数，其中2个是基于我在模块顶部的一对reg压缩数组中定义的值，如下所示：< / p>
reg[31:0] k [0:63] = '{
32'hd76aa478, 32'he8c7b756, 32'h242070db, 32'hc1bdceee,

和
reg[4:0] s [0:63] = '{

我在实例化这样的模块时访问这些值：

有没有人有任何建议？我可能正在初始化数组错误，或者也许verilog不支持基于数组值定义参数，但我对此表示怀疑。是否有更高的资源来定义我的参数？我不会在这个生成序列之外使用这些数组中的值。 ＆＃34; K＆＃34;可以用函数来定义，我可以使用它，但s不能。
答案 0 :(得分：1)
k和s定义为要编译的参数。最简单的解决方案是将reg更改为parameter并启用SystemVerilog。 Verilog不支持解压缩参数数组或解压缩数组语法'{}。要使Verilog补充，您需要将k和s更改为单个打包数组（也称为向量）。
k是一项相对简单的变更：reg [31:0] k [0:63] = '{ - ＆gt; parameter [32*64-1:0] k = {
s类似，但您需要为正确打包的所有条目添加前缀5（否则verilog会将7视为32'd7）
parameter [64*5-1:0] s = {
5'd7, 5'd12, 5'd17, 5'd22, 5'd7, 5'd12, 5'd17, 5'd22, 5'd7, 5'd12, 5'd17, 5'd22, 5'd7, 5'd12, 5'd17, 5'd22,
5'd5, 5'd9, 5'd14, 5'd20, 5'd5, 5'd9, 5'd14, 5'd20, 5'd5, 5'd9, 5'd14, 5'd20, 5'd5, 5'd9, 5'd14, 5'd20,
5'd4, 5'd11, 5'd16, 5'd23, 5'd4, 5'd11, 5'd16, 5'd23, 5'd4, 5'd11, 5'd16, 5'd23, 5'd4, 5'd11, 5'd16, 5'd23,
5'd6, 5'd10, 5'd15, 5'd21, 5'd6, 5'd10, 5'd15, 5'd21, 5'd6, 5'd10, 5'd15, 5'd21, 5'd6, 5'd10, 5'd15, 5'd21
};
索引的顺序不会颠倒。旧k[0]现在是k[64*32-1 : 63*32]。由于循环是使用常量和genvars完成的，因此您可以执行k[(64-i)*32-1 : (63-i)*32]。
hash_op #(0,s[64*5-1 : 63*5],k[64*32-1 : 63*32]) hash_op_0(
...
for(i = 1; i<64; i=i+1) begin : generate_hash_ops
hash_op #(i,s[(64-i)*5-1 : (63-i)*5],k[(64-i)*32-1 : (63-i)*32]) hash_op_i(
...
我更喜欢indexing vectors and arrays with +:所以用于计算索引的数学表达式只是一方，加上使用+:在always块和assign语句中使用变量和网络类型，并且输入更少。
hash_op #(0,s[63*5 +: 5],k[63*32 +: 32]) hash_op_0(
...
for(i = 1; i<64; i=i+1) begin : generate_hash_ops
hash_op #(i,s[(63-i)*5 +: 5],k[(63-i)*32 +: 32]) hash_op_i(
...
此策略适用于icarus verilog 0.10。我看起来像icarus verilog 0.9.7和旧有一个限制，它只能使用参数的整个值;它给出了消息＆＃34; 抱歉：无法选择参数位。＆＃34; 此策略适用于modelsim，适用于任何符合IEEE1364-2001或IEEE1800的模拟器
