feat(tools): 仿真调试台适配新版显存,并修好 xsim 里跑 python 的环境问题
tb_saolei.v / tb_saolei_play.v: - dump 从 1200 字节(1 字节/格)改成 2400 字节(每格 2 字节) - 变量地址按新 ELF 更新(g_state 0x7AC、mine_bm 0x86C、g_ncells 0x8B4 ...) - 已揭开格数直接读 opened_cnt(0x7B4),通关目标改成 g_ncells - g_mines fb2png.py: - 支持每格 2 字节(byte0 字形[5:0] / byte1 颜色[2:0]) - 字库不再手工抄表,改成直接解析 cpu21_vga.v 的 font_row(),RTL 加字模会自动跟随 - 字形 16..41 显示成 A-Z play_saolei.tcl: - 用绝对路径找系统 Python:xsim 的环境里 py 会选中 Vivado 自带的 python3.8, 报 SRE module mismatch - 清掉 PYTHONHOME/PYTHONPATH,否则系统 python 也会去 Vivado 的 lib 找模块 - render/save_shot 补 global python 实测:hard 模式 30x16 棋盘在终端正常显示,点击展开的区域横跨屏幕第 13~22 行 (含中线以下的 8 行)-> 证实 FB_WORDS 那个"只能写前 15 行"的 bug 已修好

dump 格式(tb_saolei.v 里的 dump_fb 任务生成):
|
||||
CURSOR <row> <col>
|
||||
CTRL 0x<byte> # [0] 光标可见 [6:4] 背景色
|
||||
FB 1200 # 随后 1200 行十六进制字节,按格号 0..1199
|

FB 2400 # 随后 2400 行十六进制字节:每格 2 字节(字形、颜色)
|

渲染依据(与 RTL 严格对应,改 RTL 时这两个表要同步):
|
||||
* 字库 cpu21_vga.v 的 font_row():8x8、bit7 是最左像素,放大 2 倍 = 16x16 一格
|
||||
渲染依据(与 RTL 严格对应):
|
||||
* 字库:直接从 cpu21_vga.v 的 font_row() 解析(8x8、bit7 最左,放大 2 倍 = 16x16 一格)
|
||||
—— RTL 改了字库(比如新增 A-Z)这里会自动跟随,不用手工抄表
|
||||
* 调色板 cpu21_vga.v 的 pal():3 位 -> 4:4:4 RGB(0xA 分量 = 170)
|
||||
* 显存每格 2 字节:byte0 = 字形[5:0],byte1 = 颜色[2:0]
|
||||
* 光标 cpu21_vga.v 的 cursor_box:格子四边一圈 2 像素宽的黄色框(常亮)
|
||||
* 画面 40x30 格 -> 640x480
|
||||
|
||||
另外还会在终端打印一份 ASCII 图,方便在没有图片查看器的地方快速看结果。
