Quartus2编译错误解决方法.doc

Error (10257): Verilog HDL error at dp4inNpa.v(13): unsized constants are not allowed in concatenations解决方法：拼接语句a_fout = {0,exp_a_out,temp_a_out,12'd0};其中0应标注位宽，编辑器不会默认为1位，应为a_fout = {1'b0,exp_a_out,temp_a_out,12'd0};Error (10053): Verilog HDL error at dp4inNpa.v(12): can't index object "a" with zero packed or unpacked array dimensions解决方法：错：input a; 对：input[12:0] a;Error: Net "acc[12]", which fans out to "accumulate:inst4|acc[12]", cannot be assigned more than one value Error: Net is fed by "time_get_sub:inst3|acc[12]" Error: Net is fed by "sample_en:inst6|acc_out[12]"解决方法：输入的某些引脚同时给了两个值，大概不是重复定义管脚就是重复赋值了。

Error: Top-level design entity "delta_t" is undefined解决方法：将.v文件名和module的名称改为一致Error: Inconsistent dimensions for element "tR"解决方法:"tR"在传递过程中可能丢失了"[12..0]"。
