تم تحسين placement حول STM32H743 / USB3343 / USB-C، وأعدت ترتيب مقابس الصوت J2–J9 في عمودين لتصفية تداخلات الحافة.
النتائج:
  • route-feasibility ناجح: لا توجد blockers، فقط ملاحظات advisory.
  • حاولت تشغيل auto-route، لكنه انتهى بحالة discarded ولم يطبق مسارات.
  • DRC الحالي يعرض airwires فقط لأن اللوحة ما زالت غير موجهة.
  • وثّقت الحالة في routing-attempt-status.
المتبقي:
  • التوجيه لم يكتمل بعد.
  • يجب تنفيذ التوجيه يدويًا/موجّهًا حسب الأولوية:
    1. USB DP/DM
    2. ULPI bus
    3. clock/reset/debug
    4. AK5558 TDM
    5. power/low-speed nets
الخطوة التالية الأفضل: أبدأ بتوجيه USB DP/DM وULPI يدويًا/على مراحل، ثم أشغّل DRC بعد كل مجموعة.

قم باعاده تصميم وترتيب القطع علي اللوحة في اضيق مساحة ممكنه امنه واجعل المخارج والمداخل في اتجاه الخارج للوحة حتي اذا ركب المستخدم الجاكات لا توثر عليه وتعيقه القطع الالكترونيه

flux

سأعيد ترتيب الـPCB بهدف تصغير المساحة بأمان، مع جعل USB ومداخل الجاك على حواف اللوحة للخارج وترك منطقة خالية خلف الجاكات حتى لا تعيق المكونات توصيل الكابلات.

flux

تمت إعادة ترتيب اللوحة إلى 120×100mm بدل 160×100mm، مع وضع كل جاكات الصوت J2–J9 على الحافة اليسرى للخارج وUSB‑C على الحافة اليمنى، والإلكترونيات خلف المداخل بدون إعاقة منطقة تركيب الجاكات.
المتبقي:
  • DRC ما زال يعرض airwires فقط لأن التوجيه لم يبدأ بعد.
  • فحص قابلية التوجيه أصبح جاهزًا ولا توجد عوائق فعلية؛ فقط ملاحظتان مسموحتان للـ exposed pads.
الخطوات التالية المقترحة:
  1. توجيه USB DP/DM أولًا.
  2. توجيه ULPI بين USB3343 وSTM32.
  3. توجيه TDM بين AK5558 وSTM32.
  4. تشغيل DRC بعد كل مرحلة.
