在当今快节奏的世界中,半导体设计的创新是一项永恒的需求。对更快、更准确、更创新的解决方案的需求为探索生成式人工智能(#GenerativeAI)在半导体设计开发领域的潜力铺平了道路。能做到吗?当然可以!在本系列文章中,我们将深入探讨令人兴奋的实验,展示生成式人工智能如何彻底改变半导体设计。
实例 1 - 从 FSM 图到 SV 代码
在本例中,谷歌的生成式人工智能模型--BARD 被用来生成一个自动售货机 FSM 的 SystemVerilog 实现。

代码如下:
// Vending machine FSM // Disclaimer: This code is not tested for correctness module vending_machine ( input clk, input reset, input coin_inserted, input product_selected, input product_dispensed, output reg dispense_product, output reg return_coin ); // Define the states localparam [2:0] IDLE = 3'b000; localparam [2:0] COIN_INSERTED = 3'b001; localparam [2:0] PRODUCT_SELECTED = 3'b010; localparam [2:0] PRODUCT_DISPENSED = 3'b011; localparam [2:0] OUT_OF_STOCK = 3'b100; // Define the registers reg [2:0] current_state; // Transition logic always @(posedge clk or posedge reset) begin if (reset) begin current_state <= IDLE; end else begin case (current_state) IDLE: begin if (coin_inserted) begin current_state <= COIN_INSERTED; end else begin current_state <= IDLE; end end COIN_INSERTED: begin if (product_selected) begin current_state <= PRODUCT_SELECTED; end else begin current_state <= COIN_INSERTED; end end PRODUCT_SELECTED: begin if (product_dispensed) begin current_state <= PRODUCT_DISPENSED; end else if (out_of_stock) begin current_state <= OUT_OF_STOCK; end else begin current_state <= PRODUCT_SELECTED; end end PRODUCT_DISPENSED: begin current_state <= IDLE; end OUT_OF_STOCK: begin current_state <= IDLE; end endcase end end // Output logic always @(posedge clk) begin case (current_state) PRODUCT_DISPENSED: begin dispense_product <= 1'b1; end default: begin dispense_product <= 1'b0; end endcase end always @(posedge clk) begin case (current_state) OUT_OF_STOCK: begin return_coin <= 1'b1; end default: begin return_coin <= 1'b0; end endcase end endmodule
